Federal Railroad Administration

rosaP Repository & Open Science Access Portal

The Federal Railroad Administration (FRA) promotes safe and environmentally sound rail transportation. The FRA conducts research and development tests to evaluate projects in support of its safety mission and to enhance the railroad system as a national transportation resource. Public education campaigns on highway-rail grade crossing safety and the danger of trespassing on rail property are also administered by FRA.

    Yin, S. K.
    1975-02-01 | PDF
    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 be ...
  • Proposed qualification requirements for selected railroad jobs
    Proposed qualification requirements for selected railroad jobs
    Hale, A. (Allen), 1938- ;
    Jacobs, H. H.
    1975-01-01 | PDF
    This report proposes minimum safety-related knowledge, performance and training requirements for the jobs of railroad engineer, conductor, brakeman and train dispatchers. Analyses performed were primarily based upon job and task analytic documentation already in existence, and were critically reviewed by government and civilian railroad specialists ...
  • Comparison of Thermally Coated and Uninsulated Rail Tank Cars Filled With LPG Subjected to a Fire Environment
    Comparison of Thermally Coated and Uninsulated Rail Tank Cars Filled With LPG Subjected to a Fire Environment
    Townsend, William ;
    Anderson, Charles
    1974-12-01 | PDF
    Two fire tests were conducted on 128 kiloliter, high pressure rail tank cars filled with liquefied petroleum gas. 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 insulatin ...
  • A Methodology for Evaluating the Economic Impacts of Applying Railroad Safety Standards Volume I
