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.

  • Bridge Approaches and Track Stiffness
    Bridge Approaches and Track Stiffness
    Davis, David ;
    Plotkin, Donald
    2008-02-01 | PDF
    Over time, it is not uncommon for a dip in the track to develop off the end of a bridge—on the bridge approach. This dip, or bump at the end of the bridge, is often a rough-riding spot and one that requires resurfacing at more frequent intervals than does the rest of the track. A commonly held belief is that this dip in the track is caused by dynam ...
