Wheel Failure Mechanisms of Railroad Cars: Appendices

This report summarizes an extensive research program into the causes of wheel thermal failure. Results of material property tests, review of failure data, dynamometer tests, roll dynamics unit, track tests, and theoretical and experimental stress analysis show that heat-treated wheels of designs...

Super-Speed Ground Transportation System: Las Vegas/Southern California Corridor Phase II

[From the Preface] This report presents the findings of two separate studies of the feasibility of providing Super Speed Train service between Las Vegas and Southern California. The work was funded by a Federal Railroad Administration grant that required local matching funds. The local share was...

Summary of Accidents Investigated by the Federal Railroad Administration: Calendar Year 1984

The 1984 Summary of Accidents Investigated by the Federal Railroad Administration (FRA) includes 214 railroad accidents. This summary provides the following information: the railroad(s) involved, the location and the time of the accident, the type of railroad accident, the method of operation and...

Railroad Safety Research and Development: 1987 Prospectus

[From the Preface] This Prospectus was assembled with the intent to provide a document that would serve as the basis for informing interested parties of the contemporaneous research being conducted by the Office of Research and Development, Office of Safety, Federal Railroad Administration.

Inductive Interference in Rapid Transit Signaling Systems, Volume II: Suggested Test Procedures

Methods for detecting and quantifying the levels of inductive electromagnetic interference produced by solid state rapid transit propulsion equipment and for determining the susceptibility of signaling systems to these emissions are presented. These methods include procedures for taking...

Impact of Railroad Contracts on Corn, Wheat and Soybean Bids to Elevators and Farmers

This report presents the results of research conducted to determine the impact of destination and origin railroad contracts on grain bids to elevators and farmers. The impact of destination contracts on grain bid prices to elevators was estimated by comparing bid prices for rail delivered grain at...

High Performance, High Cube Covered Hopper Car Program, Transit America's HI CUBE 2000 Car Dynamic Performance Tests, Summary Report

As part of the co-operative Track-Train Dynamics High Performance, High Cube Covered Hopper Program, Transit America provided a prototype car - the HI CUBE 2000 for dynamic performance tests under the program's performance guidelines. This new design car was tested to evaluate its dynamic...

High Performance, High Cube Covered Hopper Car Program, Base Car Dynamic Performance Tests: Volume 4 - Summary

This report presents a summary of the dynamic performance tests of a 4750 cubic foot capacity high cube covered hopper car. All the tests were conducted at the Transportation Test Center in Pueblo, Colorado. Results of the reduction and analysis of test data for the rock-and-roll, pitch-and-...

Determinations of Dynamic Fracture Toughness Properties of Rail Steels

Motivated by the occurrence of a long-running rail web fracture in service, dynamic fracture mechanics research was undertaken to (1) quantify the crack driving force due to the residual stresses induced by roller straightening operations, (2) determine dynamic fracture toughness values for rail...

Classification of Hazardous Materials in Rail Transportation

The regulations pertaining to the classification of hazardous materials in rail transportation were examined for their robustness in identifying hazards, the classification of hazardous materials, and the utility of these classifications to those who must deal with rail accidents involving...
