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.

    2019-12-01 | PDF
    The wheel/rail (W/R) interface experiences variable friction conditions during in-service operation. This is due mainly to the application of top-of-rail friction modifiers, gage face lubricants, and other third-body materials that exist at the W/R interface due to non-controlled environmental factors (e.g., rain, ice, plants, etc.). Friction acts ...

  • Mixed Freight and HigherSpeed Passenger Trains Framework for Superelevation Design
    Mixed Freight and Higher-Speed Passenger Trains: Framework for Superelevation Design
    Dick, Tyler C ;
    Ruppert, Conrad
    2019-10-01 | PDF
    As the demand for higher-speed passenger trains increases, the disparity between freight and passenger operations also increases. On mixed-use rail corridors, the result is a bi-modal distribution of train speeds that complicates design of curve superelevation. To aid in making informed curve superelevation decisions on mixed-use rail corridors, th ...
