AB - This report is a compilation of documentation on the methodologies of state rail planning in Wisconsin and Michigan which was specifically prepared for FRA for later input to a manual on state rail planning. These states subsequently are using their respective methodology in establishing their rail plans pursuant to the Federal assistance requirements of the Regional Rail Reorganization Act of 1973 (PL 93-236). The report is structured so that the reader can go through the rail planning process and select for in-depth study, a step of particular interest. Initially, it focuses on goal development and constituency identification. Considerable attention is given to the collection, use and analysis of data relating to rail traffic and costs, and to the existing rail plant. The reader is given the option of two different approaches towards analyzing the prevailing problems endemic to light density branch lines. A thorough discussion of evaluating the need for rail passenger service is also included. Upon publication of manual on state rail planning, additional material on policy planning and implementation will be developed. There will also be current information on special problems such as urban rail relocation, yard and terminal consolidation, and state participation in rail safety. A detailed and comprehensive bibliography on rail planning will be included.

TASK 3. TRACK AND STRUCTURES STANDARDS DEVELOPMENT PY - 1975/09 SP - 355 p. AB - Track and structure characteristics and problem areas to be encountered in upgrading the Corridor are discussed. Standards considerations and applicability are outlined along with the maintenance history of the Corridor. Track system options for application to 150 MPH High Speed Rail (HSR) service are discussed and performance records examined. Concrete ties, fastener systems and ballastless track (concrete slab) are considered with wood tie track in a structural and cost effective investigation. Factors of type and frequency level of HSR train service and potential joint usage with freight movements are projected for these analyses. With this information, design parameters such as lateral and vertical track stability are investigated and established. On basis of structural integrity, selected track system candidates are costed over a 50 year life cycle of construction and maintenance. All projected maintenance items are described in detail with cycle rationale delineated.

TASK 7B - SHOPS AND YARD FACILITIES PY - 1975/09 SP - 242 p. AB - The purpose of the report is to formulate functional design criteria for 'CorridorRail' revenue vehicle inspection, servicing, maintenance and repair for locomotives, cars and right-of-way maintenance equipment including signal and communication equipment. The purpose is to assure that the development of maintenance and servicing techniques for the 'CorridorRail' has the full benefit of technology developed in the past as well as that currently being developed for railroad passenger service. Efficient operation of an inter-city railroad passenger service requires the availability of a completely reliable service fleet of clean revenue cars sufficient to maintain advertised schedule service, while minimizing the total number of cars required. In order to accomplish this goal, the philosophy of planned maintenance is to perform all rebuild and heavy repair at Washington Terminal, the southern terminal point of the corridor and perform service, inspection and limited repair at Philadelphia, New York and Boston.

AB - A preliminary examination of the problems associated with mixed-traffic operations - conventional freight and high speed passenger trains - is presented. Approaches based upon a modest upgrading of existing signal systems are described. Potential costs to the operating railroads, impact on railroad efficiency, and safety of passengers and train crews are considered. Special attention is given to analysis of stopping distance for various conditions and rolling stock. Basic conclusions are that speeds above 125 MPH are likely to require substantial signal system modification and that freight service capacity will be severely degraded by large numbers of HSPT's; further analysis is required to determine well-founded control-system guidelines.

VOLUME II (SUSPENSION PARAMETER VARIATION TEST REPORT) PY - 1975/08/18 SP - 103 p. AB - An additional running test program of the LTV/SIG Metroliner trucks was conducted with the objective of defining suspension system characteristics. The tests were conducted on revenue tracks of the Penn Central Railroad in the Northeast corridor between Washington, D.C. and Hudson, N.J. Testing began on February 28, 1975 and ended on May 7, 1975. A test train comprised of snack bar coach 850 and the fleet car, snack bar coach 855, was operated for a distance of 3657 miles. Test operations were conducted on 18 days, and a total of 65 runs was made. Three hundred and sixty-eight tests were conducted within the 65 runs. Tests were conducted with 21 different suspension system configurations. The final suspension system, tuned for optimum ride quality, demonstrated that Car 850 had a ride superior to Car 855. Test data also showed that Car 850 had a lower onboard noise level than Car 855. Data obtained during the test were sufficient to generate a load spectrum for the trucks and components when operated under the current Metroliner speed profile.

VOLUME I PY - 1975/08/01 SP - 117 p. AB - This report presents the test plan and results for Phase 2 tests of the LTV/SIG Metroliner Truck. Section 4.0 is the test plan which was submitted to DOT/FRA on September 5, 1974. The test plan was approved by DOT/FRA before testing began. It became necessary to amend test procedure during the test program. The changes in test procedure were approved by DOT/FRA during the course of testing, and those amended procedures are described in Section 5.0 which also presents test results. An Additional Running Test followed Phase 2 tests, and the results of Additional Tests are presented.

AB - This experimental program is a labor, management and government undertaking directed by the Labor/Management Committee. The St. Louis Terminal of the Missouri Pacific Railroad was selected as a location for testing innovative experiments in terminal operations. Temporary experimental changes are considered in any operational or regulatory aspect of the terminal. This report reflects the results and conclusions from an experiment involving the operation of a run-through train between Missouri Pacific's Neff Yard in Kansas City and the Alton & Southern's Gateway in East St. Louis. The operation of this train reduced car detention by 3.3. hours per car on an average of 53 cars a day. As a by-product of this experiment, the St. Louis Project Team helped initiate an agreement which allows certain A&S crews to haul MoPac-C&EI transfers between St. Louis and Mitchell, Illinois. Previously a crew change was required at East St. Louis. The run-through train operation lasted approximately five months before being terminated as a result of system-wide cutbacks in train operations brought on by the severe recessionary drop in carloadings during December 1974.

FINAL DESIGN REPORT PY - 1975/08 SP - 345 p. AB - The Vought Systems Division of the LTV Aerospace Corp. (LTV) in association with the Swiss Industrial Company (SIG) of Neuhausen Rhine Falls, Switzerland, has designed, manufactured, and tested the LTV/SIG Truck under contract to the Department of Transportation (DOT). The LTV/SIG Metroliner Truck design was derived from the SIG M-Type Truck. The primary design objective of the program, performed under contract to DOT, was to provide a truck having improved ride comfort at speeds to 160 mph for the Penn Central Metroliner route. The design features a welded steel frame and bolsters, a coil spring/bellcrank primary suspension, an air spring secondary suspension, and elastomeric components to minimize noise/vibration transmission. A worn wheel profile is used with its attendant advantages in wear and maintenance. Truck designs were completed to allow the use of either General Electric or Westinghouse propulsion systems. However, only the former configuration was completed through final assembly due to the unavailability of government-furnished Westinghouse traction equipment. Because most of the analysis and design was done in Switzerland, the metric notation is used extensively in this report.

AB - The ground stabilization techniques of grouting and artificial freezing are reviewed. General grouting considerations are discussed including selection of grouts and techniques of injection. Materials for both particulate and chemical grouts are described along with their influence on ground properties and advantages and disadvantages. Artificial ground freezing is discussed in terms of techniques of freezing, strength-deformation and thermal considerations, and advantages and disadvantages. Selected case histories which illustrate the application of grouting and freezing to tunnel and shaft construction are briefly summarized.

AB - A preliminary examination of the problems associated with mixed-traffic operations - conventional freight and high speed passenger trains - is presented. Approaches based upon a modest upgrading of existing signal systems are described. Potential costs to the operating railroads, impact on railroad efficiency, and safety of passengers and train crews are considered. Special attention is given to analysis of stopping distance for various conditions and rolling stock. Basic conclusions are that speeds above 125 mph are likely to require substantial signal system modification and that freight service capacity will be severely degraded by large numbers of HSPT's; further analysis is required to determine well-founded control-system guidelines.

AB - A truly comprehensive analysis of any ground-tunnel liner interaction problem requires that the three-dimensional nature (geometry, stress and displacement fields) of the problem be considered. This report describes an investigation undertaken to study the complex distribution of stresses and displacements mobilized around and along unlined, partially lined, and completely lined tunnels being advanced through soils of various stress-strain behaviors. Circular tunnels with a depth to diameter ratio of five were considered. The unlined and lined tunnel analyses were divided into three subgroups on the basis of the simulated stress-strain behavior of the soil. One series of analyses considered linear-elastic behavior and involved the consideration of two different elastic modulus values and three different Poisson's ratio values. The soil in a second subgroup was assumed to exhibit elasto-plastic behavior corresponding to a shear strength independent of the mean stress and the angle of shearing resistance. An additional series of elasto-plastic analyses considered soil behavior to be a function of both cohesion and the angle of shearing resistance. The finite element program GEOSYS was used in this investigation. The excavation and construction options of this computer program made it possible to simulate, with a minimum of effort, a tunnel being advanced through an initially stressed ground mass.

AB - The report describes a computer-aided analytical approach to estimation of the potential benefits, costs, and implementation associated with allocation of grade crossing safety resources. Three types of information are required as input: (1) the grade crossing population, categorized by hazard, location (urban/rural), and existing warning systems; (2) warning system alternatives, characterized by cost and effectiveness; and (3) criteria for acceptable or preferred resource-allocation strategies (required benefit-cost ratio, total resources available, number of fatalities to be prevented, etc). A computer program has been prepared that determines all solutions meeting stated criteria and characterizes them in detail (specifying warning systems for each crossing category). Operation is highly interactive, and requires only seconds of computer time. Examples are presented based upon national statistics, and cases are chosen to indicate sensitivity to uncertainties in input data.

AB - This study was undertaken to determine the behavior of steel fiber reinforced, quick-setting cement concrete and provide information on these materials for application in tunnel liners. The use of expansive cement, special fiber geometries, fiber orientation by vibration and postcracking behavior in compression as related to tunnels are briefly discussed. A Catalog of Standard Mixes for tunnel liner concretes in introduced. Strength, handling time and elastic properties are reported for pumpable mix designs with 3/8-in. (10-mm) maximum-sized aggregate with regulated-set cement and 0.9, 1.2 and 1.5 volume percent steel fiber reinforcement. Durability studies show that low void volume, pumpable mix designs are less permeable than mix designs proportioned by conventional methods. Sulfate resistance studies indicate that the quick-setting cement concrete studied to date deteriorates sooner than type 1 cement concrete in a particular sulfate environment. Regulated-set cement concrete heated to 660 F (350 C) retain 30 to 40 percent of their original strength after cooling. Available research on corrosion of fiber reinforced concrete is reported and a research program is suggested.

AB - The problem of analyzing the capability of a rail line to absorb additional traffic has become increasingly important recently as various means of consolidating and expanding usage of the rail systems have been proposed. This report develops a systematic procedure for evaluating the potential capacity of a wide variety of rail line haul facilities under a number of operating conditions and policies. The procedure is based upon a parametric analysis of a series of rail line cases or operating and physical plant scenarios simulated using a computer train dispatching model. This report first briefly describes the simulation model. Next the structuring of the approach to the analysis is presented along with a description of the cases and the results of the case simulations. Then a parametric analysis of the results is described and procedures for applying the analysis to other conditions are developed concluding with a sample application. Finally, concluding observations are discussed and recommendations for application of the results and for further research are presented.

AB - Fiber reinforced, quick-setting cement concrete mix designs are suggested for use in the development of a prototype liner system. These mix designs can meet the structural and durability requirements of the tunnel liner and can be placed in a slipform by pumping. The mix designs are governed mainly by the fact that the mix must be pumpable. Aggregate shape and gradation are critical. A mix with a high likelihood of pumpability can be formulated by adherence to a procedure based on prevention of segregation failure, the most common pumping failure mode of fiber reinforced concrete. Fiber reinforced concrete mixes proportioned for pumping are of high strength, by normal standards, because of the paste content necessary for workability. Conventional pumping equipment is believed adequate for placing properly designed fiber reinforced concrete mixes if components are selected to minimize line head losses and minimize remolding of the concrete. Mixes for a specific field application should be tested for set times, pumpability and strength, using field procedures for batching, mixing, and placing, prior to actual field use.

AB - A series of 18 steel ribs with 10 ft-radius arches and 7-ft straight legs were tested to investigate the effect of loading geometry, eccentricity of load, and various section shapes used for making the ribs. It was found that symmetrical loading about the rib center line gives higher rib capacity and that closed section shapes resist eccentrically applied loads much more effectively. Square structural-tube ribs filled with concrete and one square structural tube rib with sleeve connections were tested. The practicality of using ribs made of closed-section telescoping segments is discussed. It is found that the greatest problem with ribs of this type is the tolerances required in the manufacture of sections that must slide within one another. Sleeve connections are evaluated and it is found that tolerances in section sizes are also a problem in making this type of connector practical. A study of steel rib behavior with variation of blocking stiffness and connection stiffness is described, using a computer analysis. These parameters were constant in the test series described above. Finally, results of the tests on ribs are compared with the analysis commonly used for design and is found to predict their behavior with reasonable consistency.

AB - Tests of three circular segmented steel-fiber-reinforced concrete tunnel liners are described. They were 10 ft outside diameter and loaded with hydraulic rams in a manner that approximates a ground loading. There were six segments and a key in each ring and the segments were ribbed to allow bolting them together. Two tests were on single rings of segments and the third was on 3 rings bolted together. A series of beams that were designed to fail in shear and made of steel-fiber-reinforced concrete were tested. The results are used to develop a means for predicting shear strength of liner segments subjected to moment and thrust as well as shear. Segment joints similar to those used in the liner tests were subjected to eccentrically applied thrust in a testing machine so that thrust and moment were present in varying combinations at the joint. These joints were also cast of steel-fiber-reinforced concrete, and methods are presented to calculate their strength. These methods are then compared with the test results.

AB - The placement of shotcrete by the dry-mix process and the engineering properties of shotcrete, typically used for underground support, were investigated in detail. Processes and quality control aspects of shotcrete, previously taken for granted, were described, evaluated, and, where possible, quantified. Coarse-aggregate mixes of conventional shotcrete, steel fiber shotcrete, and regulated-set cement shotcrete were tested successfully underground using typical crews and equipment. Documentation included water-cement ratio, high-speed photographs of the airstream, x-rays of fibrous shotcrete, and special rebound tests that determined the change in rebound with thickness. The most important parameter affecting the measured value of average rebound was the total thickness shot. The process of rebound was described in detail qualitatively and in terms of newly-defined parameters. The economics of rebound was discussed. Compressive, flexural, and pull-out tests were conducted through an age of six months. Moment-thrust tests were also conducted.

This report documents these four tests, which will provide baseline data for evaluation of future locomotive front structure modifications designed to attenuate the severity of the grade crossing accident. The automobiles were all 1973 standard size sedans of the same model with similar options. For each test, a 130-ton Alco locomotive impacted a stationary automobile at a nominal 50 mph. The first two tests contained no instrumentation on either the locomotive or automobile except for high-speed cameras. The last two tests were instrumented repeats of the first two tests which also involved a direct side impact and a side impact centered on the automobile front fender. The last two tests had an anthropomorphic dummy in the automobile and over 50 accelerometers installed in it. Each test had extensive high frame rate photographic coverage.

AB - This executive summary reports the significant findings and recommendations of a project to analyze the nationwide magnitude and nature of urban railroad relocation and prepares a methodology for future relocation studies. Three other volumes report the results in detail. Volume 2 is a guide for preliminary assessment of the potential for planning/ Volume 3 is a detailed quidebook for planning/ and Volume 4 presents a nationwide estimate of the nature and magnitude of urban railroad relocation. The investigators found that there is a conflict between communities and railroad operations that evidences itself in delays and added costs to highway users at grade crossings, hazards to the safety of the community, community barriers, environmental degradation, incompatible land use, and reduced railroad efficiency. Relocation or consolidation of railroad facilities are potential remedies for the conflict. The nationwide cost of relocating railroad lines in all places where there is a potential conflict is estimated at $3 to $11 billion. However, if projects are restricted to locations where substantial benefits accrue, the program will be closer to $2 billion. Railroad yards could also be relocated with substantial benefits, but at an additional nationwide cost of $1 billion. The high cost of individual projects deters communities and railroad companies from undertaking beneficial projects, so financial assistance and incentives are recommended to encourage relocation projects.

AB - The describing function method of analysis is applied to investigate the influence of parametric variations on wheelset critical velocity. In addition, the relationship between the amplitude of sustained lateral oscillations and critical speed is derived. The non-linearities in the model include the difference in rolling radii as a function of lateral displacement of the wheelset from its mean position, profile conicity, and gravitational stiffness in the lateral and yaw directions. The proposed method is validated by applying it to a wheelset example cited in the literature. Comparable results are obtained using the proposed technique. The describing function method presented in the report is quite general and is applicable to dynamic models exhibiting severe non-linear characteristics in profile. Critical speed, frequency of limit cycles, gravitational force, effective conicity, gravitational stiffness and creepage, etc., can be easily computed using the proposed algorithm.

AB - Previous studies indicate that one promising avenue to grade-crossing motorist-warning systems, offering lower cost and independent of railroad-track circuits, is use of a radio-communication link for signal activation. By this means, the presence of a train approaching a crossing can be communicated to the crossing from an appropriate distance. This study describes analysis, development, and test activities carried out at the Transportation Systems Center to determine the basic feasibility and practicality of a microwave realization of this approach. A brief review of the conceptual framework is followed by detailed discussion of field-test procedures and results, with special attention then given to train detectors, microwave-propagation aspects, use of solar power, and radar train detection.

BALLAST AND FOUNDATION MATERIALS RESEARCH PROGRAM PY - 1975/07 SP - 179 p. AB - Literature and other information sources pertaining to properties of granular materials, ballast and sub-ballast materials, fine-grained soils, and structural behavior models were reviewed. Presented in this report is a summary of the current technology relative to the following: (1) procedures for evaluating ballast and subgrade material properties; (2) factors which influence ballast and soil material properties; (3) relations between ballast and soil material properties and track system behavior and performance; (4) applicability of structural analysis models to predicting behavior of track system; (5) transfer functions relating track behavior to performance. Based on the review, it is concluded that ballast and subgrade materials receive inadequate considerations in analysis and design, more realistic models are available for structural analysis of track systems, transfer functions relating track behavior to performance are not available and climatic factors exert a significant influence on behavior and performance and must be given appropriate consideration in analysis and design of the track system.

AB - A study of the effect of applied stress on the wave velocity (acoustoelasticity) of railroad rail steel has shown that a potentially useful technique exists for the nondestructive measurement of longitudinal stresses. The detection of extreme stress levels would contribute toward increased rail safety by decreasing accidents due to track buckling and weld pull aparts in continuously welded rail. Velocity variations between various new rails and between new and used rails were found to be significant. The overall effect of this is expected to be minimized by either establishing a base line velocity profile for rail or by comparing the velocity change of two waves, each experiencing a different change with applied stress.

SEVENTH PROGRESS REPORT PY - 1975/06 SP - 140 p. AB - This report describes the progress of the Rail Engineering and Test Support Program during the period July 1, 1974 to June 30, 1975. Primary emphasis of the program was placed on the establishment of a viable operational track measurement capability. This emphasis resulted from efforts to meet the requirements of the National Track Inspection Program under implementation by the FRA's Office of Safety. Also covered in this report are special tests performed by the FRA test cars; operational improvements to the test car track measurement instrumentation; improvements in data-processing techniques that permit an analysis of track conditions in a more timely and more efficient manner; and highlights of other efforts performed under the Rail Engineering and Test Support Program.

LITERATURE SEARCH. VOLUME I PY - 1975/06 SP - 124 p. AB - This document serves as an introduction to the literature known to be available and relevant to rail freight car trucks, their components and performance characteristics. In connection with the Federal Railroad Administration sponsored research in Truck Design Optimization a literature search was conducted to review and assemble all relevant publications, papers, and articles. The collected documentation has been organized into five sections: (1) The History of the Freight Car Truck; (2) Truck Design; (3) Truck Companents; (4) Track-Train Dynamics as Related to Truck Performance; and (5) Truck Performance. Each section contains; an introduction dealing with literature selected for reprinting, reprints of articles judged particularly representative or salient, and a bibliography alphabetized by author. The five sections have been organized into three-volumes. Volume I contains the sections entitled: "The History of the Freight Car Truck" and "Truck Design." Volumes II and III will complete the compilation. It is expected that supplements to the three initial volumes will be published at a later date as additional information becames available.

TASK 5. ELECTRIFICATION PY - 1975/05/16 SP - 291 p. AB - The report describes existing equipment and physical conditions within the Corridor. After establishing performance objectives and design standards for the upgrading of existing systems and the construction of new electrification facilities, it examines the voltage and frequency alternatives available and identifies the most cost-effective solution. Estimated costs, for each alternative are presented. Environmental aspects are referenced, alternative traction power supply and distribution systems are reviewed, and the status and dynamics of catenary systems are analyzed from first principles. The report closes with an economic analysis of the electrification alternatives.

AB - The Oberretl theory of the double-sided linear induction motor (LIM) is examined, starting with the idealized model and accompanying assumptions, and ending with relations for predicted thrust, airgap power, and motor efficiency. The effect of varying the maximum transverse harmonic order on the transverse primary current density and airgap flux density is considered. The Oberretl theory is seen to lead to excessively large flux densities in the regions adjacent to the primary which results in an overestimate of the normal attractive forces at small motor slip frequencies. A comparison of the LIM forces predicted by the Oberretl and Elliott models is given for the Tracked Levitated Research Vehicle (TLRV) and the LIM Research Vehicle (LIMRV) LIMs. The Oberretl theory gives thrust in good agreement with those of Elliott for the LIMRV; for the TLRV, the Oberretl theory predicts thrust about 20% greater than those predicted by Elliott. The corresponding normal forces predicted by the Oberretl theory were approximately three times greater than those predicted by Elliott. A computer program developed as part of this study program is given in the appendix. It requires computing times of the order of 50 seconds for typical runs consisting of ten case points.

AB - Prediction of wheel displacements and wheel-rail forces is a prerequisite to the evaluation of the curving performance of rail vehicles. This information provides part of the basis for the rational design of wheels and suspension components, for establishing criteria for maintenance of track and wheels, for use as a guideline for safety standards, and for understanding the mechanism of noise generation and wheel-climbing. The analysis presented here extends the results from linear steady-curving appropriate to flangeless guidance, and provides a foundation for the examination of the details of forces and displacements under more severe conditions necessary to the understanding, prevention, and suppression of undesirable effects.

AB - Some basic aspects of the friction-creep phenomena in the rolling of a steel wheel on a rail are studied with a qualitative analysis of stress, strain, adhesion and creep in the contact zone and the stresses on the remaining surface of the rail and the wheel. Some pertinent literature on the subject is briefly discussed. A friction-creep test facility was modified and improved to give more accurate friction-creep data. The electrical control and drive system was changed to give accurate speed of rotation and to dynamically brake the two wheels separately. Friction-creep data was taken with braking of both the small and the large wheels. The data obtained with small wheel braking showed higher coefficients of friction than that of the large wheel braking. Some preliminary reasons for the difference are qualitatively discussed. A preliminary study of the nature and progress of wear during rolling was done with two microscopes, installed for each wheel. With the help of a microswitch and flash gun, some qualitative observations were made on one spot on the wheel. Attempts are being made to study the nature and rate of wear quantitatively.

VOLUME I. ANALYTICAL MODEL PY - 1975/05 SP - 84 p. AB - The report describes an analytical approach to estimation of fuel consumption in rail transportation, and provides sample computer calculations suggesting the sensitivity of fuel usage to various parameters. The model used is based upon careful delineation of the relevant physical machanisms of energy dissipation under steady-state conditions-rolling and aerodynamic resistance (using the Davis equations), braking, idling, and locomotive power generation and conversion losses. Both simple and more complex formulations are applied as appropriate. Several classes of service are considered: branch line freight, intercity freight, conventional and high-speed passenger, and commuter. Numerous graphs illustrate typical results for specific fuel consumption as a function of speed, grade, power/weight, load factor, weight per seat, etc. KW - Bearings KW - Braking KW - Braking performance KW - Cargo transportation KW - Commuter service KW - Computer programs KW - Diesel engines KW - Drag KW - Energy consumption KW - Energy requirements KW - Equations KW - Freight transportation KW - Fuel consumption KW - Grade operations KW - High speed rail KW - Locomotive operations KW - Mathematical models KW - Passenger transportation KW - Railroad transportation KW - Rapid transit KW - Rapid transit railways KW - Rolling resistance KW - Train operations KW - Train performance UR - https://trid.trb.org/view/29124 ER - TY - RPRT AN - 00099842 AU - Johnson, M R AU - IIT Research Institute AU - Federal Railroad Administration AU - Transportation Systems Center TI - ANALYSIS OF RAILROAD CAR TRUCK AND WHEEL FATIGUE. PART I - SERVICE LOAD DATA AND PROCEDURES FOR THE DEVELOPMENT OF FATIGUE PERFORMANCE CRITERIA PY - 1975/05 SP - 146 p. AB - The development of fatigue performance standards for freight car truck components and wheels requires a knowledge of the fluctuation service load environment, and a basis for stating the conservatism of the design with respect to the environment. On this program special emphasis was given to determining the load environment by analyzing data from 53 test runs conducted on the Erie Branch test track of the Bessemer and Lake Erie Railroad. A number of test parameters were varied, such as speed, type of truck, modifications to the suspension system, etc., to determine those parameters having the greatest influence on the severity of the load. Vertical loads were measured at the side-frame-pedestal/roller-bearing-adapter interface and lateral loads were determined at the wheel/rail interface. The cyclic load data are summarized in a series of load spectra. Factors which must be considered in the development of fatigue performance standards from these spectra include reliability goals, the statistical spread of both load and fatigue strength data, and the philosophy followed in the design of the truck itself.

AB - Flashing xenon strobe lamps were installed on locomotives in revenue service as a means of alerting motorists to the hazards they are approaching at a rail-highway grade crossing. Effectiveness of these lights in attracting motorists' attention was evaluated. The reactions of both motorists and locomotive crews to the use of strobe lights were also evaluated. Field observations, interviews, and experiments confirmed the attention-getting value of locomotive-mounted strobe lights used in revenue service to alert motorists and suggested operational procedures and device specifications that are the subject of a separate application guideline report. Experimentation and observation of the strobe lights under railroad operating conditions verified that these lights do not interfere with perception of trackside signals or with normal motorist and crew operations. The work reported in this document supports a technical recommendation favoring use of strobe lights on more extensive research tests in railroad operational service.

AB - Available mileage counters were evaluated, anticipating the possibility of using mileage intervals, rather than elapsed time, for freight car inspection. Simple, reliable and reasonably low costing devices were required. Only two unpowered mileage counting odometers were uncovered, one built in the U.S., the other in Switzerland. The Swiss device is not currently available in this country, presumably because of its particular suitability to European style trucks. The American built device was tested in eccentric rotation and for accuracy at both low and average freight car speeds. It was concluded that the American unit could serve satisfactorily in freight service, without modification, at what would appear to be acceptable cost levels.

TASK 7A. TERMINALS PY - 1975/05 SP - 515 p. AB - An essential element of any intercity passenger transport system is the interface with local transportation--both public and private. In recognition of this critical interface, a major task was undertaken to recommend a development program for upgrading fourteen major rail passenger handling terminals in the Corridor. The program was designed to meet overall goals and objectives of convenience, capacity, attractiveness and other level-of-service characteristics commensurate with high quality transportation facilities. The report consists of terminal performance standards, inventories of existing terminals and vicinity access/egress facilities, and recommended concept development plans for the terminals, parking facilities and urban transportation infrastructures in which they are located. Preliminary estimates of costs associated with the development plans are also included.

AB - This experimental program is a labor, management and government undertaking directed by the Labor/Management Committee. The St. Louis Terminal of the Missouri Pacific Railroad was selected as a location for testing innovative experiments in terminal operations. Temporary experimental changes are considered in any operational or requlatory aspect of the terminal. This report presents the results and conclusions from an experiment which temporarily waived a 1940 agreement which requires that the hauling of traffic between MoPac's east and west side yard facilities at St. Louis across Municipal Bridge be divided on a 50%-25%-25% basis between Dupo, 23rd Street and Lesperance crews, respectively. Because this rule does not reflect the present distribution of Trans-River traffic, this experiment allowed terminal management to use the best situated crew for each Trans-River movement. Analysis of this experiment indicates that the relaxation of the provisions of the Trans-River Agreement has not induced the operation of additional trips across the river, but it has stimulated terminal management to improve the utilization of transfer crews by having them haul cars in both directions across the river more frequently. During a 20-week measurement period, Dupo crews made 45% of the Trans-River trips, 23rd Street made 35% and Lesperance Street made 20%. These results indicate that the percentages provided in the agreement are no longer suited for the present traffic pattern. This experiment also resulted in the savings of about three days per month clerical effort and eliminated the confusion and dissension involved in balancing the Trans-River trips.

The losses have generally occurred following puncture of a tank in a derailment or from rough handling in terminal operations. Subsequent ignition of escaping lading frequently has resulted in the development of a general conflagration, often accompanied by the violent rupture and rocketing of other fire-exposed pressure tank cars. This report provides the basis for defining practical and economical safety improvements and identifies the safety research gaps which must be closed before a prototype tank car can be designed to optimal safety/economic considerations. Increased safety can be realized by decreasing the probability of an initial puncture, and/or decreasing the probability of subsequent tank ruptures of other cars from fire exposure. Six areas were given particular consideration because of their greater potential for success for 112A/114A series tank cars. These were: 1) operational changes, 2) head shields, 3) modified couplers, 4) thermal insulation, 5) tank material changes, and 6) safety relief system modifications. Head shields and modified couplers were found likely to be "cost-beneficial." The expense/loss reduction break-even points as a function of coating life were determined for thermal shield materials. A safety relief valve, which is actuated by excessive lading temperature and then remains open until reduction to ambient pressure, was found to have high potential for being cost beneficial. Other tank car research is reviewed and an improved thermal model for calculating the effects on a tank car exposed to fire is presented. It was found that full scale fire test results confirmed earlier analyses indicating substantial underestimation in existing design calculations of potential heat loadings to fire-exposed cars. In general, economic impact of mandated changes in over-the-road and terminal operating procedures may be expected to be greater than that of a car design change to achieve the same safety objective. Neither change may be "cost-beneficial" when this term is interpreted to mean zero negative impact on car profitability or commodity transport cost. On the other hand, it was found that a modification increasing the cost of a tank car by 10 percent tends to increase the delivered cost of LPG, for example, only on the order of 0.5 percent. Therefore, substantial expenditures could be made for car improvements with relatively little -- but not zero -- overall economic impact. Substantial improvements in car safety appear to be feasible without resort to the use of exotic materials or fabrication techniques which could not be accommodated by existing tank car manufacturing facilities.

AB - The Yamamura theory of the double-sided linear induction motor (LIM) excited by a constant current source is discussed in some detail. The report begins with a derivation of thrust and airgap power using the method of vector potentials and theorem of residues. The LIM thrust computed via the theorem of residues is compared with similar results obtained using numerical integration. Both methods are seen to yield equivalent results providing the increments in the numerical integration are made sufficiently small. The finite width and length of the primary alter the LIM thrust considerably in the regions of large and small slip frequencies, respectively. The effect of finite primary dimensions on LIM thrust is discussed in detail for the examples of the Tracked Levitated Research Vehicle (TLRV) and LIM Research Vehicle (LIMRV) LIMs operating at rated speeds. A comparison of thrusts predicted by the Yamamura, Oberretl, and Elliott LIM models for the TLRV and LIMRV motors shows fair agreement in the value of thrusts predicted by the different theories.

VOLUME I. TEXT PY - 1975/04 SP - 137 p. AB - Analysis techniques, a design procedure and design data are described for passenger vehicle, simply supported, single span and multiple span elevated guideway structures. Analyses and computer programs are developed to determine guideway deflections, moments and stresses and vehicle accelerations resulting from a two-dimensional vehicle with finite pad length front and rear suspensions traversing a multispan elevated guideway. A preliminary design procedure is described to estimate guideway beam structural requirements so that a vehicle-guideway system will meet specified levels of passenger comfort. Design data for 150 mph and 300 mph intercity 40,000, 80,000 and 120,000 lb. air cushion vehicle single and multiple span (span lengths of 50 to 150 ft.) guideways is summarized. For both urban and intercity operating regimes, the data indicate that improvements in the vehicle suspension and the use of multiple span structures rather than single span structures may result in reduced guideway material requirements.

AB - A survey is made of various inductive systems proposed for low frequency train communication. It is found that thick dielectric jackets or coaxial and metallic shields may be required to reduce the environmental effects that lead to high attenuation. Twisted wire cables with inversely connected coupling antennas attain reduction of induced electrical noise and of radiated fields. External noise interference in various environments is discussed. Analysis is made of the coupling variation effect due to wire separation.

AB - This report, the fourth in a series of four volumes produced on urban railroad relocation, describes the nature of the urban railroad location problem and estimates its magnitude nationwide. Costs of urban railroad/highway conflicts are estimated at $800 million annually to highway users in delays and increased running costs, and $185 million in accidents. Annual railroad costs are estimated at $75 to $100 million for slowing and accelerating trains in urban areas and $70 million for maintenance of grade crossing surfaces, marking, and warning devices. Community costs from environmental degredation, barrier effects, and incompatible land uses are high but difficult to quantify without detailed site studies. About two-thirds of the 2,500 communities with railroads in the U.S. with populations over 5,000 in 1970 show evidence of serious railroad conflicts that might be ameliorated by some combination of the following measures: consolidation or relocation of railroad lines; closing of dangerous, low, volume crossings; installation of improved crossing surfaces and warning devices; construction of grade separation structures (including elevated or depressed railroad sections); and encouragement of compatible community development. Programs are outlined for major relocations or consolications in an estimated 600 to 1100 communities, at a cost of up to $2.8 billion, that would return between $4 and $4.4 billion in present value of reduced highway user, railroad, and community costs. The need for Federal and State support of such a program is explored.

TASK 10S. GRADE CROSSINGS AND FENCING, WASHINGTON, D.C. TO NEW HAVEN PY - 1975/04 SP - 134 p. AB - The report identifies the status of the current program for the elimination, separation, or other complete protection of all grade crossings along the Northeast Corridor (NEC) from Washington, D.C. to New Haven, Connecticut, and develops an overall plan for the completion of fencing of the railroad right-of-way. The plan includes fencing of overpasses and provides cost and schedule information. State grade crossings separation programs were evaluated with respect to the state's projected construction schedules to determine the impact on the overall NEC project. The benefits resulting from grade separation include both safety benefits and non-safety benefits. Typical guide specification for standard chain link fence was developed for immediate and future requirements and is included as an appendix.

TASK 1. DEMAND ANALYSIS PY - 1975/04 SP - 124 p. AB - Engineering, technical and financial studies have been performed: (a) to assist the Federal Railroad Administration in the development of detailed improvement plans, and (b) to provide inputs to the United States Railway Association for the development of the preliminary and final plans. As a basis for developing detailed improvement plans, performing operational simulations, selecting and sizing physical facilities, and estimating costs, estimates are required for future service needs covering all types of rail traffic in the Northeast Corridor, i.e., passenger services-CorridorRail, suburban and inter-corridor; and freight services-intra-corridor, inter-corridor and local. The findings and estimates derived from the demand analysis are given in this report for 1990 high and low potential demand levels.

AB - This experimental program is a labor, management and government undertaking directed by the Labor/Management Committee. The St. Louis Terminal of the Missouri Pacific Railroad was selected as a location for testing innovative experiments in terminal operations. Temporary experimental changes are considered in any operational or requlatory aspect of the terminal. This report presents the results and conclusions from an experiment which temporarily waived an agreement giving crews at Ivory Yard exclusive rights to perform yard-to-yard transfer work between Lesperance and Ivory yards. The experiment permitted Lesperance crews to make transfers between these yards in addition to the Ivory crews who previously had exclusive rights. As a result of the experiment the number of transfers from Lesperance to Ivory increased by 50%/ the number of transfers from Ivory to Lesperance remained unchanged. The impact on car movement was dramatic. The average elapsed time from arrival Lesperance Street to arrival at Ivory was improved by at least 10 hours per car on a movement of about 200 cars/week. This represents a 33% decrease in the transit time for this traffic. Customers served from Ivory Yard also observed faster and more consistent movement of cars to and from industry. Based upon the favorable results from this experiment, the labor and management parties involved are negotiating an agreement to allow Lesperance crews to transfer cars to Ivory Yard.

PHASE I PY - 1975/03 SP - 189 p. AB - The report describes the features and requirements of an improved demand information and forecasting system. The following conclusions were reached: the level of demand is inadequately measured; shipper demand is highly variable, often ranging from plus or minus 50 percent of the average; because of the high purchase price of freight cars, it is prohibitively expensive to respond to these short-term variations in demand by maintaining a sufficient inventory of empty cars to accommodate the highest level of demand at each location; the time lag to recognize and react to change results in many orders being filled late and some amount of business lost to alternative transportation modes; and the size and the impact of the time lag can be reduced if potential surplus and deficit areas can be predicted and car flows adjusted to reduce imbalances before they occur. A demand information and forecasting system is being designed and evaluated on the basis of this study.

VOLUME 13. COSTING IN RAILROAD OPERATIONS: A PROPOSED METHODOLOGY PY - 1975/03 SP - 79 p. AB - The report identifies, evaluates and recommends criteria for the application of economic analysis in areas relating to data and information requirements in railroad freight operations. The demonstrated need for a more consistent and comprehensive application of this analysis resulted in the accumulation of additional data from which cost functions were estimated which might be used by railroad managements and government agencies as a basis for subsequent policy decisions. This research which was conducted at both interfirm and intrafirm levels of analysis produced a set of models calibrated from selected data encompassed in a matrix which were used to estimate production functions and appropriate long run cost functions. These models hopefully will provide valuable assistance to railroad companies as additional sources of information regarding the cost performance of their operation.

AB - The railroad industry's Labor/Management Committee, which is comprised of the chief executives of railroads and labor organizations, has established a number of labor/management programs to work on specific problem areas. The St. Louis Terminal Project is one such activity. This report elaborates on the objectives, techniques and progress that has been made. A Task Force on Terminals was established by the Labor/Management Committee with the objective of increasing the reliability, speed and efficiency of car movements through a major existing railroad terminal without capital expenditures. This objective is being achieved through a series of experiments involving changes to terminal operations. Missouri Pacific St. Louis Terminal Division was selected as the laboratory for this experimentation. A Project Team was formed to head up the project. The Project Director and Associate Director were recruited from the ranks of management and labor. Early in the program it was realized that a formal analytical search should be undertaken to identify these changes in operations that will make the most appropriate experiments. To facilitate problem identification and the measurement of quantitative impact of experiments, a computerized car movement evaluation system was developed which is described in Appendix A of this report. Several experiments involving both labor agreements and operating practices have been completed which have significantly improved car movements within the terminal. As a result, negotiations between labor and management are now in progress for the purpose of revising these agreements and operating practices.

REPULSION SCHEME. VOLUME II. APPENDICES A - F PY - 1975/02 SP - 142 p. AB - This report summarizes the studies of a program to establish the technology of magnetic suspension for ultimate use in a passenger-carrying high-speed ground transportation (HSGT) system - at speeds on the order of 134 m/s (300 mph). Magnetic Levitation (MAGLEV) is one of the advanced vehicle suspension concepts considered as alternatives to conventional transportation modes in the short-haul regime. This volume presents some details of the mathematical analysis associated with the MAGLEV vehicle dynamics and control (i.e., ride quality) in Appendices A through D; the noise or acoustic characteristics associated with the baseline Hamilton Standard Q-fan air propulsion system (Appendix E); and the Raytheon final report for the linear synchronous motor (LSM) studies (Appendix F).

Magnetic Levitation (MAGLEV) is one of the advanced vehicle suspension concepts considered as alternatives to conventional transportation modes in the short-haul regime. This third volume contains the computer programs for the solution of the equations of motion for 5 degrees-of-freedom, and a summary of the analytical background. These programs provide the capability for performing stability analyses of magnetically levitated vehicles, and for evaluating vehicle response and ride quality characteristics for operation over guideways with irregularities. Each program is listed along with a sample run. The programs are written in BASIC language for use on time-sharing systems.

VOLUME I. TECHNICAL REPORT PY - 1975/02 SP - 118 p. AB - A methodology and a computer program, DYNALIST II, have been developed for computing the response of rail vehicle systems to sinusoidal or stationary random rail irregularities. The computer program represents an extension of the earlier DYNALIST program. A modal synthesis procedure is used which permits the modeling of subsystems or components by partial modal representation using complex eigenvectors. Complex eigenvectors represent the amplitude and phase characteristics of rail vehicle systems which occur as a result of wheel-rail interaction, heavy damping in the suspension system and rotating machinery. Both vertical and lateral motion are handled by the program which allows up to twenty-five component and fifty system degrees of freedom.

CLASSIFICATION YARD ACCIDENTS PY - 1975/02 SP - 74 p. AB - A number of railroad accidents have been aggravated by couplers puncturing the shell head of hazardous material tank cars. Development of means for identifying possible puncture mechanisms and quantifying the coupler forces involved is the subject of this report. A mathematical model, capable of simulating train action in the vertical plane, has been developed and used for simulation of three classification yard accidents. A detailed description of the model and the results of simulation are presented. The conclusions of this report must be considered tentative until the results of verification studies become available.

AB - This report is an Executive Summary of FRA report OR&D-75-21 which summarizes studies to establish the technology of repulsion magnetic suspension for ultimate use in a passenger carrying high speed ground transportation (HSGT) system - at speeds on the order of 134m/s (300 mph). A baseline revenue system is described in terms of vehicle/guideway configuration, system performance and cost. Levitation and guidance is provided by eight superconducting magnets. The magnetic fields interact with a pair of L-shaped aluminum guideway elements. Propulsion alternatives are discussed but this is the area where much work remains to be done to provide adequate performance and cost data for a final selection. This technology, designed to free ground transportation from the speed and noise limitations imposed by steel wheel on steel rail, will make possible the short trip times of planes with the huge capacity of trains. Both speed and capacity are essential to meet the demonstrated demand for rapid travel in the nation's congested corridors.

AB - This report summarizes the studies of a program to establish the technology of magnetic suspension for ultimate use in a passenger-carrying high-speed ground transportation (HSGT) system - at speeds on the order of 134 m/s (300 mph). Magnetic Levitation (MAGLEV) is one of the advanced vehicle suspension concepts considered as alternatives to conventional transportation modes in the short-haul regime. These advanced systems have the potential of alleviating the heavy traffic congestion predicted for the highly populated regions of the U.S. in the 1985-1995 period. The national energy shortage has intensified the search for more energy-efficient and cost-effective transportation modes. This volume summarizes the analyses and designs which demonstrate the performance of the system including the ability to meet the DOT ride quality standards on straight and level guideways as well as on curves and grade transitions. Conceptual designs and costs are shown for the vehicles, guideways, and the complete system. Various propulsion systems and guideway configurations are investigated, and a simple economic model is developed for the evaluation of MAGLEV systems on a cost per seat-mile or cost per passenger-mile basis.

AB - Two alternate attraction magnetic suspension systems are compared on a magnetic performance basis as well as on their lift-to-weight (L/W) capabilities. On an equal current basis, the lower reluctance, flat track configuration has higher lift force and better L/W than the U shaped track configuration with its larger leakage flux. With equal magnetization (unequal currents) and low guidance forces, the U shaped track has a higher L/W ratio, but both attraction systems suffer from low L/W when all elements of the suspension system are considered.

AB - Several analytical methods for investigating the problem of vehicle/guideway dynamic interactions are presented. These methods include several digital programs, each tailored to solve a particular aspect of the vehicle/guideway problem. Also included are computerized frequency domain methods for rapid estimation of system sensitivity to principal parameters and for use in selecting candidate guideway parameters. The major tool is the full scale vehicle/guideway dynamic interaction simulation, TRAVSIM, which includes coupled vehicle/guideway dynamics, independently generated guideway roughness profiles, and data processing for obtaining vehicle output data in the various ride quality formats. An example of the use of these methods to analyze the effects of guideway roughness and flexibility on a specific vehicle is illustrated. Roughness parameters are given in terms readily understandable to guideway contractors and include camber, pier settlement, pier survey error and surface finish. Results show that it is possible to vary roughness and cross section parameters and tolerances while achieving equivalent vehicle performance. Therefore, it seems possible to allow the guideway contractor to select the least costly set of tolerances to achieve the specified ride quality.

AB - The report is a preliminary evaluation of the technical feasibility of using iron-cored, synchronously operating motors to propel ground transportation vehicles in the high cruise speed range. A second consideration is the possibility that the motor might also provide strong attractive and lateral forces. Three motor types, all realizable with passive track rails are investigated: (a) claw-pole synchronous motor, (b) homopolar inductor motor, and (c) heteropolar inductor motor. A rail clearance of 1.5 cm is specified. However, the effect of variations in this and other design parameters is also analyzed. All three types considered compare favorably with an equivalent single-sided induction motor, insofar as weight, efficiency, and power factor are concerned. The calculations are supported by analog simulation experiments.

The massiveness and large volumes of transport, the necessity for accurate regulation of tens of thousands of railway cars and locomotives, and the realization of control over a continual process of transport requires the improvement and perfection of the organization for control of the operation of the road. An optimal system of control can be ensured under conditions of wide application of mathematical and economical methods and electronic computational technology, that is by creation of an automated system of control over the operation of the railroad ASUZHT). In order for ASUZHT to effectively fulfill the functions of normalization, computation, analysis, planning, and control, it is necessary to prepare cadres, accurately define all tasks, create an insurance portion of ASUZHT which includes an informational base, a technical means complex, and the mathematical ensuring of the system in order to solve tasks in established time periods with the least possible expenditure of labor. The preparation of cadres for normal functioning includes not only manning and preparation of personnel connected with immediate maintenance and repair, the elaboration of programs, procedures, treatment and processing of information, but also the corresponding preparation of controllers, those who carry out work in the enterprises, departments and management centers on the road and who are concerned with the preparation, collection, and transmission of production information.

This is connected with the possibilities of the presently utilized means of computational and data transfer technology. Experience on several roads revealed the need and possibility for constructing more flexible automated systems ensuring the reception by train traffic controllers of operational integrated information and railcar flows and locomotives under conditions of changing train circumstances. The following functional steps can be defined in the operational control process, corresponding in equal degree to all levels of control (stations, terminal, section, division, and entire road): control over the fulfillment of the transport process, technological and technical normalization, planning (current, etc.) and actual control corresponding to various levels (type of train, autodispatcher, station autodispatcher). This report goes on to cover the collective system, by which users located at distant points have, through the data transmission devices (terminals) immediate access to the data information bank in the computer's memory, for solving tasks within a realistic time range.

AB - During the operation of cars and locomotives with roller bearings, oscillations in the bearing components produce slight fatigue flaws which are invisible to the human eye. These can lead to bearing failures on the road with consequent journal failures. During maintenance of these bearings in shops, inspections of components may reveal only obvious defects. For detection of fatigue flaws in the early stages of development, a reliable technology of flaw detectors is indispensable. This booklet describes the fundamental principles of magnetic flaw detection for appraisal of roller bearing components during their repair. Included is a description of basic equipment in the shops for insuring highly reliable inspection. The brochure is intended for shop and maintenance workers concerned with flaw detection. Chapters include statement of the task; basic information about principles of flaw detectors; flaw detection equipment for freight car wheelsets and inner races of the roller bearings; disassembly of roller bearing components for inspection during overhaul; and magnetic particle flaw detectors.

Over the last four years of the five-year plan the volume of transport on this road increased by almost 40% and in 1974 had already attained the level planned for the end of the five-year plan. In order to cope with the growing volume, electronic computational technology was widely used, allowing the simultaneous calculation of quickly-varying circumstances, the choosing of optimal variants of planning, control, and production of transport. An automated control system (ASU) for operation of the road, created on the basis of computers and mechanisms for the remote transmission of information significantly accelerates the reception and increases the reliability of a great amount of information necessary for the optimization of control over the transport process. A series of engineering and calculation tasks connected with the planning and control of main line operations are also solved. With the help of the computer monthly transport plans are worked out; on the basis of the dispatchers' announcements freight handling is elaborated according to type of cargo, department, and entire road. This report also includes a section on planning the operations of the classification yards, the collaboration of workers of main line and industrial transportation, and the experience of initiators of competition, and unique technology.

This applies to electro-physical parameters, the incombustibility of antiacid stability, and the temperature range of operational capability, which has special significance in the case of utilization of liquids in transformers installed on fire- and explosion-hazardous objects, aircraft, water and underwater vessels, etc. The study examined the properties of various types of synthetic oils (liquids) which appear promising as regards application in transformer construction. These types are oils based on synthetic hydrocarbons and oils based on chlorinated hydrocarbons. The figures and charts include the basic indicators of synthetic hydrocarbon oils, the influence of the structure of alkylbenzyl transformer oils upon their oxidation rate in the electrical field at 95 degrees C., and physical heat characteristics and relative prices of various types of synthetic liquid transformer oils.

This work investigates the reflecting shadow method of flaw detection with the utilization of integrated and divided induction coils of the electromagnetic acoustic converters (EMAC). With such a means of control it is possible to isolate two zones in the rail: the web and its continuation into the head and underside and lateral portions of the head. Checking of the first zone is most expediently realized by the EMAC, whose inductor ensures the excitation of the ultrasound oscillations distributed according to the standard of the ground surface. The indicated construction of the EMAC allows for the emission of predominantly transverse waves. The conclusions reached are: (1) For the successful revelation of defects in the web of the rail and its continuation into the head and the underside, the polarization plane of the transverse wave should be oriented normally to the plane in which the development of a defect is expected; (2) The utilization of a transverse wave polarized perpendicularly to the plane of development of the defect allows the exposure of defects not made apparent during inspection by longitudinal waves in the presence of the contact modification of the ultrasonic flux; (3) The proposed designs of the induction coils of the electromagnetic-acoustic converter and the arrangements for sounding of the rails allows the exposure of defects of vertical fissures and separations in the rail web, as well as inclined transverse fissures of fatigue, friable areas, and horizontal separations in the lateral portions of the rail head.

The temperature of heating is defined as the sum of the temperatures of the aerial environment and the overheating of the lead caused by currents of the charge. The most difficult conditions for heating up of the leads arise with the conjunction of the maximal temperature of the surrounding environment and the minimal speed of the wind. On the basis of an analysis of the maximal temperature of the aerial environment and the minimal wind speed for a ten year period for the Trans-Siberian main line from Novosibirsk-Chelyabinsk-Moscow there was obtained an estimated air temperature in the summer period of +35 degrees C. at minimal wind speed I m./s. Dependences obtained on the basis of calculations of heat characteristics allow the choosing of optimal distances between the electrical junctions according to the criterion of the best utilization of the profile of all leads of the chain suspension. The choice of the indicated distance is carried out in coordination with the current of the hourly operating mode of the electrical trains being handled on that section.

The TsNII7MA sectional insulator was developed with such insulating inserts: it is high-speed and universalized (unified) and can be applied on direct (3-6 kV) as well as alternating (15-25 kV) current, and also at junction stations. It is intended for installation in catenary suspensions with one as well as two catenary leads; and it ensures normal passage of the current collectors at speeds up to 160 km/hour (tested at speeds up to 180 km/hour). Its length is 2.9 m, its mass--31 kg. The essential advantage of this insulator over more perfected insulators presently used in the USSR and abroad is the presence of three pairs of long arc arresting horns which ensure its safe operation in emergency modes (during passage of the current collector along the insulator, when one of the sections of the catenary network is switched off or grounded), as well as with a significant variety of potentials in the sectionalized sections of the catenary network of both alternating and direct current. The sectional insulator TsNII7MA is a USSR invention; it has been patented in France and Iran.

Both tank cars were exposed to an intense hydrocarbon fire after being outfitted with appropriate instrumentation. The instrumentation was monitored and its output recorded throughout the fire tests. To test the feasibility of insulating railroad tank cars to protect them from fire exposure, one of the cars was coated with a 0.318 cm thermal shield. A comparison of data conclusively shows that a thermal shield significantly alters the thermal response of a rail tank car in a fire environment.

The profilometer is used to measure rail profile at high speeds, relative to an inertial reference. Design details and analysis of the profilometer are covered, and comparisons are made between profilometer measurements, mid-chord measurements, and manual measurements made with stringline and roll-ordinator devices, to show the relative accuracy of the profilometer measurements. The inertial profilometer offers several advantages over the currently-used mid-chord syystem. Accuracy of the profilometer has proven to be quite good. Operation of the profilometer is not degraded by inclement weather, and system components are not subject to damage by protruding objects in close proximity to the rail being measured.

AB - The excavation of an underground opening produces changes in the state of stress which cause deformations composed of both time-dependent and time-independent components. In some soils and rocks the time-dependent component of deformation is large. Internal structural supports are provided to limit the creep displacements, resulting in an increase in the radial stresses acting on the supports. The increase depends on the creep propensity of the soil or rock. A creep testing system (CTS) is developed to simultaneously perform four consolidated-undrained triaxial creep tests on cylindrical specimens. The CTS consists of: triaxial cells; lever-arm loading mechanisms; cell pressure-control panel board; temperature-control water baths; load, pore pressure and deformation measuring devices; and data logger system. The testing program consists of a series of twenty five step-type creep tests which were performed on samples of kaolinite and slaked Cucaracha clay-shale. The influence of testing conditions, such as loading procedure, magnitude of consolidation pressure, overconsolidation and secondary compression, on the creep behavior of clays was investigated.

AB - Practical aspects of the application of analytical techniques to geotechnical problems are reviewed with emphasis on medium-support interaction problems in underground structures. It is recognized that the analysis should be carried out in several stages, reflecting the initial state of stress in the medium, the construction process and the period of operation. A finite element program called GEOSYS that is capable of performing this type of analysis is described. The capabilities and the limitations of this and other current analytical techniques in regard to the multi-stage analysis are discussed. The results from a series of two-dimensional, plane-strain, finite element analyses of medium-liner interaction for a circular tunnel are presented. Three types of medium properties are considered, namely, linearly elastic, elasto-plastic and time-dependent. Also considered in these analyses is a simple sequence of excavation and liner placement. A comparative study of the effect of the material properties on the liner forces is made.

AB - A study was performed to assess the feasibility of using a focused CO2 laser beam to cut the gage of a hard-rock tunnel being excavated by a continuous tunnel-boring machine. Laser rock-kerfing tests were conducted on isolated samples of granite, diabase and quartzite rock with a Navy-owned electric-discharge CO2 laser located at the United Aircraft Research Laboratories. The tests were performed to verify previously made extrapolations which were used to predict full-scale power requirements for the laser gage-kerfing concept. Laser powers and kerfing speeds were extended from previously tested maximum values of 5 kW and 21.2 cm/sec to 16.5 kW and 125 cm/sec. In addition, the test program included a comparison of the use of 50.8 cm-focal-length spherical and cylindrical focusing mirrors.

Comparisons of electric and diesel traction investments and overall costs indicate that railroads would not only derive operating savings and benefits, but also reduce diesel fuel consumption by over 50 percent if wide scale electrification were to be adopted. There would be associated balance of payment and national security benefits to the nation and price stability benefits to the railroads. This stability would come with increasing use of coal and nuclear generated electric energy.

PY - 1974/10 SP - p. 10-15 AB - Despite the legislation and bureaucratic structure that controls the railroads and the inability or unwillingness of management to use pricing as a primary means of adjustment to changing technology, railroads have retained many inherent advantages as a transport mode. In elements such as time, convenience, public esteem and political power they have moved down in the hierarchy of values common to the U.S. public. The potential of railroads in reducing both energy costs and pollution can be realized only through efforts capable of overcoming all the interests that have gained by keeping railroads from becoming more competitive. The author concludes that whatever is done to shift freight and passenger traffic to railroads will become piecemeal.

It reduces the line source emissions from highways and diesel trains to single stationary point source which may be in nonurban areas that can be more easily controlled. There could also be a reduction in noise pollution. If rail electrification involves coal fuel there would be a new range of air pollutants and the problem of reclaiming lands immediately after strip mining. Of importance, say the authors, is obtaining accurate information on energy conversion efficiencies for electrification, and comparative environmental, energy and economic impacts of alternative intercity transportation modes.

The states need also to undertake rail planning and research as part of the overall planning process. Although the railroads, as private enterprise, occupy a different relationship to the transportation planning process than publicly owned systems such as highways and airports, the states are sincerely looking to railroads for cooperative planning in the creation of multi-modal transportation systems for both goods and people that would be more efficient than what exists now.

In the railroads' weighing of two options, electrification or continuation of diesel operation, the author introduces what he terms the Corporate Hurdle Rate, a return sufficiently above the weighted incremental cost of capital so that new investments at this level will overcome the low earnings of present sunk investments. He notes that the economics of two options should be analyzed and if there is an acceptable option, then the cheapest source of financing should be secured. Introduced also is the technological risk factor. Finally the author speculates on whether the only choices should be diesel or electric operation.

In comparing truck and rail, it is noted that there is not much difference between the two when pickup and delivery type operations are involved. Substantial opportunities for improved fuel economy do exist in linehaul operations where the railroads' fuel economy is undisputed. Examined are merchandise traffic, bulk materials and intermodal services. Greater use of piggyback, it is concluded, has to be the primary means of effecting a reduction in freight energy consumption.

Carbon content of the wheels is shown to be the principal factor which controls their toughness. One hundred wheels which fractured in service are analyzed by means of fracture mechanics procedures. The locations, configurations, and size of thermal and plate cracks which initiated brittle fracture are reviewed, and estimates made of the stress levels which resulted in failure. Estimates have been made of the minimum size of crack which could result in the failure of wheels under adverse service conditions. These are discussed with respect to the minimum size of defect which can be reliably detected by NDT.

AB - The design of truck bolster center plate rims was investigated as a result of increased reports of their failure on 100-ton capacity freight cars. The damage occurs when cars are coupled at moderate to high speeds, since the rapid deceleration of the truck causes high loads between the truck and body bolsters. Test measurements were made on an unloaded 100-ton hopper car impacting a string of loaded cars. The forces between the truck and body bolsters on the moving car were determined at impact speeds from 2.9 to 9.2 mph. Tests were made with two different energy absorbing capacities of draft gear. Loads at the truck-bolster/body-bolster interface averaged approximately 40,000 lbs for impact velocities up to 5 mph and reached 100,000 lbs at 7 mph. A peak load of 160,000 lbs was measured at 8.4 mph. Within the lower speed range there were no significant differences in load associated with the two draft gear, but at 6.7 mph the loads with the higher capacity gear were 25 percent less. Strain gages placed near the center rim indicated yielding on the first impact at 2.9 mph. Additional yielding continued as the impact velocity was increased. A finite-element stress analysis showed that loads of the magnitude measured on the test would cause severe stresses in the center plate rim and that yielding of the material would be expected. Several potential modifications of the truck bolster center plate rim were analyzed which showed that significant improvements could be obtained by making the rim wider and by increasing the radius of the fillet at the inside of the rim.

AB - The lateral stability derivatives of a dynamic ram air cushion vehicle in a rectangular guideway were measured using a ship model towing tank. Lift and pitching moment are also reported. The primary lateral derivatives are all stabilizing, with significant cross coupling in some cases. The longitudinal forces are compared with the numerical prediction of the one-dimensional mass conservation theory given by Boccadoro, with good agreement. A trailing edge Trefftz analysis is presented and used to predict the lateral derivatives. Comparison with the lateral data is good for side displacement derivatives but is less successful for yaw angle derivatives. The towing tank is found to be an effective method for testing dynamic air cushion vehicles.

AB - This study was undertaken to determine the behavior of steel fiber reinforced, quick setting cement concretes and provide information on this material needed for its application in tunnel liners. Strength-time and creep behavior are evaluated for specific mix designs. The creep behavior does not appear to be substantially different than for plain concrete. Interaction diagrams are presented for concretes made with Duracal cement and fiber contents of 0.9, 1.2 and 1.5 percent by volume. Various failure modes were obtained depending on the initial relative eccentricity of load. Tensile stress-strain relationships are analytically obtained from flexural test data. These relationships make possible a post-crack analysis of a fiber reinforced concrete structure. Fiber content, fiber orientation, and type of cement have little effect on Poisson's ratio but do influence the modulus of elasticity and the strength. Durability of these concretes is examined through study of permeability, leaching, volume stability, disturbance of young concrete, effects of high temperature environments and sulfate resistance. Pumping of fibrous concrete is investigated through laboratory testing. The presence of fibrous reinforcement significantly increases the volume of voids making the aggregate gradation and cement paste content critical parameters in designing pumpable mixes.

The purpose of the report is to develop forecasts of future rail freight volumes that are classified as "overhead" or "through" freight and those that either originate or terminate in the St. Louis Region and are referred to as "local" freight. The assumptions and methodology used to obtain the forecasts are discussed along with the application of the Multi-Regional Input-Output Model (MIRO). The forecasts are used as input to the AAR Network Simulation Model and, in addition, the local freight forecasts are used in conjunction with projects of future industrial locations patterns within the region to develop a freight generation map. Industrial locations patterns are obtained from the DYLAM II Model which allocates future growth in land uses based on the supply of sites meeting specific physical and environmental criteria.

LOUIS REGION PY - 1974/06 VL - 4 AB - This report on "Economic Factors - St. Louis Region" for the Comprehensive Areawide Railroad Consolidation and Relocation Study contains an analysis of the key demographic and economic characteristics of the St. Louis region as well as the results of a preliminary investigation of riverfront redevelopment potential. Past trends in key indicators - population, households, income, employment, residential and nonresidential construction, and retail sales - are identified and analyzed. Projections of these characteristics are presented to the year 1995. The information to be derived from this work recognizes the fact that improvements to the railroad system within the St. Louis region and the potential for the development of released land will take place within the context of the economic resources and constraints operating within the region. The various demographic and economic factors add to and/or detract from the region's ability to take advantage of the benefits to be achieved through railroad-associated redevelopment. A summary of Riverfront economic conditions is presented along with a discussion of constraints upon redevelopment and preliminary findings on reuse opportunities.

AB - Studies are described that were directed toward improving the design of certain types of tunnel support systems. Studies to predict the interaction of a circular liner with the medium performed with a linear finite element computer program and a closed form solution are described. Two construction techniques that give different interaction solutions and thus different liner loadings were simulated. Results are presented in the form of dimensionless plots from which moment, thrust, shear and deformation can be predicted. Steel-fiber-reinforced regulated-set-cement concrete has been proposed for use in a slipformed tunnel liner system. Mix design, pumping characteristics and mechanical properties of this material are described. Also, test results for two specimens which represent a portion of the slipformed liner are presented. Behavior of the liner and resisting mechanism was found to be highly nonlinear and to have a great deal of reserve strength beyond the linear range. Eleven large-scale tests which simulate steel horseshoe sets in rock tunnels are described and the effects of connection characteristics, blocking stiffness, load distribution and load inclination on the set behavior are discussed. Both the concrete liners and the steel sets that were tested, were simulated by a linear (STRUDL) and a nonlinear analysis (NASTRAN) and the results compared with those obtained from the tests.

AB - An analytical and experimental investigation of the static and dynamic behavior of nearly full scale pleunum-type air cushion suspensions is described, including the effects of compressor-duct dynamics and secondary suspension characteristics. The results indicate that cushion-duct interactions may strongly affect cushion stability unless the lowest resonant frequency of the duct is much higher than the cushion unsprung mass natural frequency. Criteria are suggested for selecting appropriate duct models for use in suspension dynamic analysis. For most practical systems a second- or at most fourth-order duct model will adequately represent the distributed duct dynamics.

The system was assembled at the U.S. Navy testing grounds, China Lake, California to prove the design concept and feasibility of transferring high-electrical power between rail and collector brushes at elevated speeds while subjected to prevailing environmental conditions. With minor modifications, the initial design conformed to specified requirements up to speeds in excess of 300 mph. Analysis of the rail configuration and test results indicated that distance between the wayside rail supports could be doubled (25 ft) lessening by half the number of supports required to maintain the rail's alignment integrity at design speeds. Installation of the wayside rail system at HSGTC, Pueblo, Colorado will be constructed using the 25 ft span configuration.

This study determines the operating regimes within which the SVS offers potential advantages over other HSGT alternatives such as high speed rail (HSR) and tracked air cushion vehicle (TACV) systems. Each system type provides an equal level of transportation service for typical high speed applications, including 200 mile intercity and 40 mile airport access corridors. Various design options concerning guideway supporting structures for above, below and at-grade construction are examined considering costs and planning and community preferences for each basic land use category. Collocation with existing transportation corridors offers the potential of significantly reduced right-of-way costs and less negative impact on the surrounding community.

Previous aspects of the program have demonstrated the technical feasibility of two types of magnetic suspensions (the attractive-force, and the repulsive-force suspensions) for such applications, and have developed a baseline design for a TMLRV (tracked magnetically levitated research vehicle). The attractive force suspension considers the development of a mathematical model which predicts the magnetic behavior of the magnet-rail system for high speed, and a parameter optimaization of the magnet. The repulsive-force suspension examines various track geometries to see if the amount of aluminum in the track could be reduced without loss of performance.

ANALYSES AND DYNAMIC MODEL TESTS PY - 1974/04 SP - 239 p. AB - This report presents the results of scale model tests and parametric structural analyses which were performed in support of a conceptual investigation of cable-stayed guideways for suspended vehicle systems (SVS). The SVS concept would use high speed ground transportation (HSGT) vehicles suspended from an overhead guideway and which could achieve large cabin bank angles for high speed turns. This cabin bank mechanism allows the SVS to maintain a high speed, even when the guideway is collocated with an existing freeway or railroad with relatively tight turn radii.

AB - High speed vehicles may operate in tunnels or tubes to minimize impact on the surrounding environment. Operation in tunnels or tubes minimizes the impact of surface obstacles, high noise levels, weather constraints and street congestion in metropolitan areas. The performance of these vehicles is significantly affected by the aerodynamics and needs to be understood. The aerodynamics of vehicles traveling through tubes are significantly affected by the constraints of the tube wall and the relative size (blockage ratio) of the vehicle. Steady flow conditions are reached only after long travel times. In this report, the flow created by vehicle travel in a tube is analyzed using numerical integration of the unsteady flow equations. Steady state conditions are rarely obtained for closed-end tubes up to several hundred miles in length. Solutions are presented for various blockage ratio vehicles with choked and unchoked flow conditions about them. Various tube lengths are also considered. The solution for a doubly infinite tube is found to be approaching the asymptotic long time solution.

VOLUME 11 IMPROVING RAILROAD RELIABILITY: A CASE STUDY OF THE SOUTHERN RAILWAY. EXECUTIVE SUMMARY PY - 1974/03 SP - 24 p. AB - This report summarizes the results of the second phase of research conducted by the Massachusetts Institute of Technology for FRA. An in-depth case study of the operations of Southern Railway verified previous research conclusions and suggested strategies for a test program for improving reliability. Results of the test, analyzed by Southern and MIT after its implementation, show both reliability and mean trip times can be improved in the short run without increasing costs. It is suggested other railroads can develop similar programs for improving reliability. Top managements must specify reliability service as a major corporate goal, have lines of effective communication and establish a mid-management interdepartmental planning unit.

AB - An analytical and experimental evaluation was made of the stability and dynamic characteristics of a small scale magnetically levitated vehicle. The vehicle was levitated over a variety of guideway perturbations in an attempt at stimulating unstable modes of oscillation. No instabilities developed in the five degrees of freedom measured using either passive or active damping. The analytical model was used to simulate the observed motions of the vehicle using a computer. Reasonable agreement was found although more damping was observed than was simulated using the model. This work was performed as a part of the Federal Railroad Administration's program of research and development on high speed ground transportation for use in intercity passenger service.

VOLUME 10. IMPROVING RAILROAD RELIABILITY: A CASE STUDY OF THE SOUTHERN RAILWAY PY - 1974/03 SP - 167 p. AB - The report serves three major functions: it analyzes O-D yard, and line-haul performance over a large portion of the Southern system; it summarizes a set of procedures for improving reliability on any railroad, and it describes in detail the test program carried out on the Southern. The major product of this research, this test program demonstrated that reliability can be improved in the short run, that this need not initially involve added capital or operating expense and that this will also result in lower trip times. By changing train schedules and operating procedures for three traffic flows, involving 300 cars/day, Southern improved reliability about 15%, reduced trip times by nearly a day, and save approximately $25,000/month in car utilization expense.

AB - A cost/benefit analysis of head shields installed on new and existing 112A/114A series pressure tank cars was performed based on a redistribution of accident dollar losses. Head shields are designed to prevent puncture of a tank car head during an accident with resulting loss of lading and possibly extensive fire damage. The design of the head shields and data for the analysis were obtained from Railway Progress Institute (RPI) - Association of American Railroads (AAR) cooperative research program reports. The RPI/AAR considered accident data for the years 1965-1970 and assigned accident dollar losses during that period according to the tank element that failed. Supporting evidence is presented indicating that dollar losses are strongly related to puncture distribution for a more extensive set of data including all classes of tank cars.

AB - This comparative analysis was an examination of the vehicle-track interactive dynamics where several types of trains are required to operate over the same route at different speeds. Two areas of concern were examined: the effects of track geometry (surface, crosslevel and alignment) on vehicle response and track loads, and the effects of lateral force components acting on curves. A linear, 14-degree-of-freedom computer model was used to simulate a number of rail vehicles on a conventional track structure of rails, ties and ballast, including the Metroliner, passenger and freight cars, TurboTrain, and several locomotives.

AB - A water cannon was fabricated and tested to evaluate its effectiveness in disintegrating rock for potential application in hard rock tunneling. Experiments were conducted in the laboratory and in field tests in a dolomitic limestone mine and in a granitic gneiss quarry. As jet stagnation pressures were increased in the range from below 100,000 to 650,000 psi (700 to 4500 Mn/sq m), the specific energy for disintegrating rock generally decreased, except for some evidence of a minimum specific energy for barre granite at a jet pressure near 400,000 psi (2800 Mn/sq m). The water cannon tests obtained specific energy values which are competitive with the best rolling cutter tunneling machines. Results to date indicate that practical application of water cannons has high potential in rock tunneling.

With the introduction of multigroup inspection it is necessary in each case to establish independently of the number of reprocessed compositions the optimal number of groups of technical inspectors and the optimal time for placing railway cars in the yard. It would be expedient to organize, at stations not having dispatching yards, "throughput" repair on a specialized classification track, or on tracks for equipment maintenance.

In this regard the contractless method of flaw detection is very promising; the ultrasonic oscillations are excited in the checked object by means of electromagnetic-acoustic (EMA) converters. Utilized in the capacity of the converter is a flat coil in the form of a spiral or a special form, onto which is fed a high frequency current impulse. The principle of excitation of the contactless ultrasonic oscillations in the rail metal is effected as the EMA converter operates in simultaneous regimen, and its feeding is realized from the impulse generator pulsations. The coefficient of the converter with contactless means of exciting the ultrasonic oscillations is much smaller than with the piezoelectric converters. Therefore, this means cannot be utilized for flaw detection by the echo method. During operation of the reflecting shadow method, it is possible to obtain several ground reflections, which show promise for contactless means for rail flaw detection.

The utilization of regenerative braking causes the appearance of negative loads in the traction network and in some cases in the substations as well. As the result of this the resulting loads on the feeder zone and, to a lesser degree, on the substations, are unequal. The greatest inequality of load is observed on suburban sections, caused by partial starting up and by short periods of energy usage by the trains. The article goes on to discuss the feeding regimen and voltage in the traction power supply, the influence of changes in voltage on the operation of the electrical rolling stock on single phase current roads, the influence of voltage on the throughput of the sections, the regulation of voltage, the longitudinal and transverse capacitance compensation, the traction networks, and their AC and Dc parameters: the calculation of instantaneous schemate, unidirectional feeding, junction feeding; methods of calculating electrical supply systems, calculation on the basis of the train traffic timetable, analysis methods; protection of the traction network from short circuit currents, and, finally, technical economic calculations of the electrical supply systems.

According to definition it is a dampening liquid, as well as a high and low-temperature heat carrier for apparatus. Organic factors for the wide utilization of polymethylsiloxane liquid PMS-10 in the capacity of dielectric impregnation of cellicular and paper-film condensers are its high stability, as well as the fact that its electrical characteristics are not normalized by the All-Union State Standard.

Nevertheless there are many deficiencies. These constructions are divided into two groups: the first includes foundations on a natural or pile base with supporting grillage foundation constructed by the traditional foundation pit method. The second group contains pile base foundations of scaffold bridges, as well as other types of foundations with slab grilling lifted over the road surface. The first group is constructed with a significant volume of earth works in permafrost soils, work in the placing of monolithic concrete, as well as with significant change of the negative character in thermal mode of the frost foundation and the soil surrounding it. These changes are connected with defrosting of the frost soil of the foundation and the walls of the pits under the influence of heat elaboration of the monolithic concrete and its exothermic nature. The article goes on to discuss various problems connected with thermal regimens, seasonal work production, and various insufficiencies connected with both types of foundations. Fulcra with foundations of a columnar type are most promising in their technical economic, technological constructional and operational indices for any frosty-soil conditions, inasmuch as they allow the full exclusion of work consuming labor on the pit foundation, the completion of concrete work at low temperatures, full mechanization of all basic processes, and a significant decrease in work expenditures.

Widely utilized in the capacity of heat-insulators for protecting the soil from freezing are sturdy foam plastics, light concrete based on foam plastics (styropore-concrete), porous clay filler processed with bitumen, compressed peat, wood crust, and other light materials. In the USSR several sections of rail and automobile roads have been constructed which are heated by foam plastics. Depending upon the thickness of the heat- insulating interlayers of this material the soil freezing process can be substantially diminished or even fully prevented. Therefore the correct definition of the heat- insulating interlayer attains very important practical significance. Data from current observations on soil freezing heated by foam plastic and other light materials bears witness that the thickness of heat-insulating interlayers depends upon local climatic conditions that mainly influence the depth of freezing of the soils, the properties of the heat-insulator (coefficient of water- permeability and specific thermal capacity) and its distribution in road constructions. On the basis of this data a formula has been elaborated by the author for determining the thickness of heat-insulating layers which fully protect the soil from freezing but can also be used for determining the thickness of heat-insulating interlayers in railroad embankments, as well as for calculating the heating of pits and others objects.

Thus on direct current sections SI-2 insulators with AG-4C plexiglass inserts are widely utilized. Alternating current sectional insulators TsNII-2 with polymer insulating elements, which are simultaneously slide blocks coming into contact with the rolling stock current collector runner, are also widely utilized. Analysis revealed that the economical effect from the application of direct current type SI-2u new sectional insulators can be summarized in the following factors: the difference in the price of the traditional insulator and the new one; the difference in the stability of installation into the catenary suspension; the difference in the service periods; and the increase in the reliability of the operation of new insulators in comparison with old ones. The economical effect in a given instance is manifested both in the production sphere and the utilization sphere on the roads as well.

Yaw constraint of the wheelsets in relation to the truck frame can then be minimized and full advantage taken of the ability of conical wheelsets to align themselves radially on curved track. This stability ensures that tread profile conicity does not change as wheels wear and stability can be maintained for long periods. South African Railways has incorporated such a diagonal suspension truck with encouraging test results. Although sharp curves are prevalent on the track where tests were conducted, flange wear has been negligible.

Because of the greater demands of today's freight service, a capability gap has developed between the truck performance required and that provided by contemporary running gear. The evolution of the three-piece truck, from the archbar design through stages to the contemporary arrangements, is illustrated. Some other car problems are covered and the possible end of cut-and-try design in running gear is foreseen. The possibility that a premium truck might be cost effective is suggested.

To achieve optimum train operation, DM&IR coupled its short ore cars in four-car sets with drawbars, introduced the Wabco straight-air retainer system, and eliminated angle-cocks and air-hose connectors where the drawbars are installed. The road uses a planned 1,188 cars assembled in "miniquads" in 124-car unit trains. With this operation so successful, attention has now turned to on-train monitoring of derailed equipment and plans for a more comprehensive real-time measurement of condition throughout any unit train. It is concluded that more can be done to improve the operational control, efficiency and safety of unit trains.

Efforts over the past two decades have led to the strengthening of critical areas of freight cars. However, the track has been subjected to increasing wear as larger and heavier cars were introduced. The beneficial effects of the railroad/supplier/government efforts, the Track Train Dynamics program will be of great importance to the industry. Until there are major fixed-plant changes, it is urged that the geometry of cars better accommodate today's track, and that the industry consider shorter trains.

AB - Squeezing ground conditions in hard-rock tunneling are associated with fault zones containing brecciated rock and gouge. The time-dependent nature of the deformation and support loads in squeezing ground conditions suggest that the creep behavior of fault gouge is the significant engineering property controlling the in situ behavior. An experimental and analytical study is presented that deals with soil creep and its application to the prediction of tunnel support requirements in squeezing ground. Support requirements given by the theoretical analysis are compared to numerous case histories obtained from the published literature. Finally, specific consideration is given to squeezing conditions at Straight Creek and Pacheco tunnels. The analysis provides a method for estimating steel support requirements for tunnels at different depths and in various squeezing ground conditions.

VOLUME 15. A MODEL OF RAIL/TRUCK COMPETITION IN THE INTERCITY FREIGHT MARKET PY - 1973/12 SP - 318 p. AB - The report proposes a model based on the logit function to predict the rail and truck market share for specific city pairs and commodity groups. Effort was devoted to the problem of introducing both transport service variables and shipper's logistic variables into the model. The model was calibrated with data from the 1967 Census of Transportation and from various carriers. Significant regressions were obtained from linear logit models once the proper variables were identified. Theoretical monetary values of carriers' services were compared to the empirical values in the model, indicating that shippers pay more for quality service than predicted; this result may be due to bias in the model introduced by use of aggregated and unreliable data. It is concluded that further research using this model form with more disaggregate data could yield significant improvements in results and provide valuable information for public and private transportation planning.

Detailed drawings and specifications have been developed for this design so that it can be constructed at the DOT High Speed Ground Test Center which is located near Pueblo, Colorado. Present plans are to extend the presently constructed 3 miles of guideway by use of the TRW/ABAM design for the next construction segment. Reductions in the structural cost of the guidway of 20-30% have been predicted. The guideway described in this report uses a continuously reinforced concrete pavement slab for the horizontal levitation surface and precast concrete panels for the vertical guidance surface. The guidance panels are attached to the slab by steel I-beams. This report summarizes the design features, design constraints, critical loads and cost estimates for this guideway structure. Also described are construction considerations and requirements for the foundation. Theoretical models and results of the static and dynamic analyses are described in appendices.

AB - A linear induction motor (LIM) operates, in principle, in the same manner as a conventional rotating induction motor. But LIM performance is subject to degration by so-called end effects, particularly at relatively high vehicle speeds (100 mph upwards). End effects are the phenomena caused by rapid generation of currents in the reaction rail at the entrance end of the LIM and their equally rapid decay at the exit end. Specific knowledge of dynamic current distribution and directional characteristics will materially aid the future design of improved LIMs. This report documents an investigation of current distribution in the LIM research vehicle (LIMRV) reaction rail at the U.S. Department of Transportation High-Speed Ground Test Center, Pueblo, Colorado.

Studies conducted as early as 1965 indicated that the TACV, in comparison with other high speed ground transportation candidates, possessed the greatest potential for implementation in the 1980's. The project began with basic technology studies and laboratory tests, and is presently in the test operations phase, utilizing a tracked air cushion research vehicle (TACRV). Test operations began with the TACV in November 1972, at the Department of Transportation's High Speed Ground Test Center in Pueblo, Colorado. A status report on the project is presented, focusing on recent test developments and future plans. In addition, the main components of the TACRV system (i.e., the vehicle, air cushion system, propulsion system, power distribution and collection system, and guideway) are briefly described.

The corridors are described in terms of socioeconomic characteristics and intercity transportation facilities and services. The characteristics of the rail routes are presented and the physical and operating constraints on improving rail service are examined. The travel patterns, and traveler characteristics and attitudes toward intercity modes are analyzed. Finally, patronage and revenue estimates are forecast for a number of alternative improved rail operations in each corridor and compared to anticipated costs of initiating and operating such services. The results are analyzed for promising corridors for demonstrations of improved rail service in terms of potential market size and market acceptance.

AB - The report examines a number of modal split models for intercity travel forecasting to determine their relative characteristics and modal share estimating capabilities for selected cases. The following calibrations of the Cross-Elasticity Model are considered: CN22, CN25, CN26, CN27, CN28B, HSGT, and SRI along with the PML abstract mode model. Using recent and more reliable travel data, the models are evaluated in terms of their ability to replicate the observed travel patterns and in terms of their implied elasticities for the rail model. Model CN27 was selected as the best overall model among those tested. This model is stratified by purpose, however, which creates a data requirement that cannot always be reliably fulfilled. Thus, the unstratified Model CN22--the second best among those tested--is recommended for use when base year travel data on trip purpose is unavailable.

AB - The United States utility industry has not set suitable standards, other than TIF (Telephone Interference Factor), for controlling the design of solid-state wayside and on-board power-conversion equipment, to limit the harmonic currents and voltages in both the transit and electric-power-supply systems. To reduce interference with telecommunications and control equipment, and to insure reliable operation of power equipment, the manufacturers can attenuate the power harmonics by selecting the converter pulse number and by the use of filters. Techniques for calculating the harmonic voltages have been developed and can be applied to transit systems. The authors propose a standard of 10% of fundamental amplitude for each harmonic voltage at the connection point to the utility and 3% for each harmonic voltage within the transit system such as the power rails.

The book also describes the interactions of the catenary suspension brackets and the current collectors during various train travelling speeds; it sets forth the fundamental processes of layout, construction, and operation of the catenary network. Great attention is paid to the insuring of operational reliability of the catenary network under all meteorological conditions and during high train travelling speeds, as well as to the raising of current output quality and the lowering of wear and tear of the catenary conductors. The catenary network must insure steady current output during highest speeds and under all meteorological conditions, and the recent raising of electric railroad speeds to 200-250 km/h led to a series of problems in the rolling stock.

Previously studied were the characteristics of this field on rails magnetized by the moving of the permanent magnet field; an image was obtained of the longitudinal defects. By means of an approximation, the significance of the eddy-current defect field was calculated. The component of the dynamic defect field caused by the magnetized rail was determined in the regular manner by static magnetization. The eddy current component was reproduced under laboratory conditions using a model. The longitudinal inductive current flowing through the rail head under realistic conditions was substituted for by a direct electrical current corresponding to the standard. Conclusions: (1) The eddy current field from rail defects differs from the magnetostatic according to the form, size and amplitude; the longitudinal component of the eddy current field resembles the vertical and transverse components of the magnetostatic field and vice versa; the components of the eddy-current field are two to three times greater in amplitude along the rail. (2) The resulting dynamic field corresponds to the model obtained by summation of the magnetostatic and eddy current fields; the resulting field of internal defects differs from the magnetostatic and resembles the eddy current while the field of joints and rail fissures is closest to the magnetostatic.

In order to calculate the transformational power, graphs of the load capability can be utilized. In addition to this it is necessary to have a stable round-the-clock graph of the load transformed into an equivalent rectangular load. However in a number of branches of the national economy, random operating regimens of consumers are encountered. The task for solving transformational power when examining the load as a random process leads to finding a mathematical expectation for the intensity relative to the wear and tear of the winding insulation. This can most accurately be accomplished by the probability modeling of the load schedule. The mathematical expectation of the intensity relative to the wear and tear can more simply and with sufficient accuracy be found on the basis of statistical characteristics of the temperature of the winding. The article concludes that the essential difference in the values of the permanent times of the winding and the oil, and the correlation times of the load, permit the proposition of sufficiently simple formulas for the definition of statistical temperature characteristics of the winding, which can in turn be utilized for finding the relative wear and tear of the insulation and calculating the necessary transformational power. The formulas obtained on the basis of the theories of random fixed functions are not connected to the type of correlational functions and the law of load distribution.

The construction of the roadbed here has a series of peculiarities, one of which is the prevention of frost reception in the soils and the formation of heavings. In winter freezing it is usual in depressions and on level spots that more or less equivalent heaving of the track occurs for great stretches, which practically does not cause inadmissible alteration of the profile. In separate places, on the strength of some or another local reasons an equivalent heaving is destroyed and its local alteration appears in the form of protruberances, indentations, or drops in pressure, generally called heavings. The observations of heavings on USSR railroads revealed that in approximately 40% of cases there are protruberances, in 57% indentations, and in 3% drops in pressure. Drying of the soil for the prevention of heaving turns out to be completely effective only when the drainages (including gutters) intercept the water of the permeable water-bearing layer which feeds the heaving soils: therefore it has a limited application.

AB - This book presents the principal bases of the theory of simultaneous statistical oscillations of the track as a system with distributive parameters, and of the rail vehicle as a system with many degrees of freedom in the vertical plane. Accepted in the capacity of perturbations are irregularities on the track and the wheels, as well as clearances between the rail and the foundation. Algorithms are given for solving the differential equations of simultaneous vertical oscillations of various fundamental types of rolling stock and track, realized on the BESM- 4 electronic computer, which can also be utilized for the solution of these tasks on the M-22- and M-222 independently of the mathematical ensuring of the specific type of machine. For a wider utilization of the various electronic computers during the dynamic calculation of the track a program is given which is also based on Fortran language and translated into the GE-400 electronic computer. New calculation methods and algorithms for solution allow to be exposed a series of new qualitative and quantitative particularities of the interaction of the vehicle and the track, especially during high traffic speeds. The book is intended for scientific and technical scientific workers of railroad transport. The chapters include (1) Task presentation. (2) Theoretical premises of calculation: mathematical model of the vehicle, equalization of the crew oscillations under the action of vertical forces applied in the wheel-rail contact, computation of the matrix of the spectral densities of irregularities, definition of average significances and mean squared deviations of basic parameters characterizing the stressed and deformed condition of the track; (3) Calculation characteristics: of rolling stock, track structures, spectral analysis of surface irregularities in the rolling of the car wheels; (4) Calculation program on the electronic computer of the interaction of the track and rolling stock under the action of vertical dynamic forces: short description, block schematic, makeup of output information; (5) Analysis of the results of mass calculations on the computer.

With correct design, and taking into consideration the properties of the material and high quality processing, such cushions are an effective and economical means for eliminating heaving. Nickel slag has been used in the construction of a second track on the Serozak-Isakovo railroad run over a 1 m. anti-deformational cushion. Asbestos by-products were used as ballast, and covered as well the basic area's shoulders. These granulated nickel slags have been used more and more widely over the past several years. They are a by-product formed during smelting of nickel ores and quick cooling of the liquified (igneous liquid) metal in granulated regions.

In these conditions the working of pits and depressions follows laborious processes of soil loosening by explosive or mechanical means. During the construction of the roadbed of secondary tracks the loosening of soils by explosion leads frequently to collapses of the operating track. Therefore there is great practical interest in the experience accumulated in the conservation of open pit soils from seasonal freezing by means of quick-hardening foam plastic on the basis of ureaformaldehyde resin. The soil heated by this method is found in a practical condition before working the open pit, thanks to which construction machines can be operated near to summer norms. The article goes on to develop a definition of the necessary thickness of the heating layer effectively protecting the soil from seasonal freezing. It is important, during design of the foam plastic insulation for depression in the secondary track, to ensure rational construction of the heat-insulating layers of foam plastic on road slopes and shoulders. The authors carried out verification calculations for wet ureaformaldehyde foam plastic with humidity of 20%.

A more complete information can be obtained using the method of a cut-out of a template, with the subsequent tensile measurement of deformations, which arise during the relieving of the residual stress. The resulting residual stress sheet on the rail surface has a very complex character. In order to determine the maximum value of residual stresses on the head surface, in the web, and in the middle part of the rail flange, a statistical processing of results of residual stresses by both methods was used. It was found that it was not possible to determine with sufficient accuracy the stress magnitudes due to the complex character of distribution of residual stresses according to slot gapping. For an approximate evaluation, one can use the value of gapping (or convergence) of the slote of the rail sample along the web.

Dynamic testing of test frogs beneath scheduled freight and passenger trains showed: (1) The cast portion of the rail wing manufactured from high manganese steel has a sufficient safety factor; (2) The movable point manufactured from special profile ramp rails, in light of its capacity, has almost a double safety factor; (3) The maximum measured transverse movement of the wheels within the limits of the frog did not exceed 1.8 mm, with a mean of 1.1 mm.; (4) The transverse forces and stresses in the resilient points during the movement of the frog agrees well with calculations. Until these tests were carried out, the permissible speed straight through a switch was 160 km/hr and for the diverging movement 50 km/hr; further testing at speeds up to 220 km/hr can be recommended.

AB - This is a comprehensive book covering the topics of ground vehicle aerodynamics, tunnel or tube and air cushion aerodynamics. It is the first book to treat all these categories, and with the current interest in new transportation systems it should have immediate use by design engineers. The complexity and diversity of topics covered presents a thorough treatment of each item. Essential features are discussed and information necessary for preliminary aerodynamic design of ground vehicles is provided. Speeds up to 300 mph are currently being considered for ground transportation systems, and at these speeds the drag, lift, and side-forces can be of the order of the weight of the vehicle. The basic principles of air cushion vehicles are given and discussed. Both plenum and peripheral jet air cushions are considered along with the effects of forward speeds. A major difficulty with the air cushion vehicle is its stability, and the author gives an introduction to the static and dynamic stability associated with such vehicles. A significant portion of this book is devoted to the aerodynamics of vehicles in tunnels and tubes. At speeds in the range of 300 mph compressible flow analysis must be used to describe some of the flow fields caused by a vehicle moving at such speeds in the confined environment of a tunnel or a tube.

AB - Staring in February 1971, Massachusetts Institute of Technology conducted a study of rail freight service reliability for FRA. With the assistance of eight major railroad, MIT first established measures of reliability, quantified current railroad performance and isolated some of the causes of unreliability. The conclusions of this phase are that unreliability does exist, that the problems are in yards, that unreliability can be improved in the short run by changes in rail operations and that a dialogue with shippers is critical.
