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.

    DeBoer, David J
    2003-03-01 | PDF
    The objective of this report is to provide an industry context for public officials who are interested in rail short haul intermodal corridors and to offer a template for analyzing related costs and benefits. Public agency analysis and investment in short haul corridors present a fundamentally new sort of challenge for public sector transportation ...
  • Evaluation of Alternative Detection Technologies for Trains and Highway Vehicles at Highway Rail Intersections
    Evaluation of Alternative Detection Technologies for Trains and Highway Vehicles at Highway Rail Intersections
    Reiff, R P ;
    Gage, S E
    2003-02-01 | PDF
    Five technologies were evaluated for their ability to detect trains and/or highway vehicles approaching and occupying highway railroad intersections. Tests were conducted on the performance of these technologies during October and November 1999 at the Federal Railroad Administration's Transportation Technology Center in Pueblo, Colorado. The catego ...
  • Crashworthiness design modifications for locomotive and cab car anticlimbing systems
    Crashworthiness design modifications for locomotive and cab car anticlimbing systems
    Mayville, Ronald A. ;
    Stringfellow, Richard G.
    2003-02-01 | PDF
    This study addressed the feasibility of incorporating complete anticlimbing systems into both passenger and freight locomotives. Complete systems include pushback couplers, vertically interlocking anticlimber elements, and zones specifically designed to absorb the collision energy. The project included the development of specifications for the syst ...
  • Analytical modelling of rail defects and its applications to rail defect management
