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.

    Reinach, Stephen ;
    Viale, Alex
    2007-05-01 | PDF
    Human factors are a leading cause of train accidents and incidents in the United States. Human factors go beyond the crew members who operate the on-track equipment. They include management support and oversight, operating practices and procedures, technologies and facilities, and the work culture—in short, the socio-technical environment in which ...
  • Repair of Budd Pioneer Coach car crush zones
