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.

    1993-08-01 | PDF
    The fracture mechanics models were refined for two types of rail defects - the bolt hole crack and the vertical split head. Beam-type finite element analysis was conducted to determine the effects of joint bar looseness, rail height mismatch and train speed on the static and dynamic components of the crack driving force for the bolt hole crack. Bot ...
