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.

  • Development of an Adaptive Predictive Braking Enforcement Algorithm Final Report
    Development of an Adaptive Predictive Braking Enforcement Algorithm [Final Report]
    Ede, Bill Moore ;
    Brosseau, Joe
    2009-06-01 | PDF
    Predictive enforcement braking is one of the key concepts behind positive train control (PTC) systems. If a train is on the verge of overrunning a target stopping location, such as an authority limit, the system enforces a brake application to stop the train safely short of the limit. The concept depends on an algorithm that can predict the stoppin ...

    The North American Joint Positive Train Control (NAJPTC), was an ambitious project to develop, test, and demonstrate PTC capabilities, including flexible block operations, interoperability, and advance activation of highway grade crossing devices, in a corridor with both freight and passenger service. The project’s safety objectives were to: a) pre ...
  • The aerodynamic effects of passing trains to surrounding objects and people
    The aerodynamic effects of passing trains to surrounding objects and people
    Lee, Harvey Shui-Hong
    2009-04-01 | PDF
    Two safety issues are raised on the aerodynamic effects of a passing train on its surroundings. First, a high-speed train passing other trains on an adjacent track exerts aerodynamic pressure that can affect the structural integrity of window mount and glazing, and the stability of the railroad car being passed. Second, as a high-speed train passes ...
  • Advanced Truck for HigherSpeed Freight Operations
    Advanced Truck for Higher-Speed Freight Operations
    Stewart, Monique
    2009-04-01 | PDF
    A major constraint for higher-speed freight trains is truck hunting, or lateral instability. The three-piece truck, a workhorse for the railroad industry for over 100 years, is inherently susceptible to hunting in empty car conditions above 45 to 50 mph. This speed limitation on any train that has an empty car leads to operations restricted below t ...

  • North American Joint Positive Train Control Project
    North American Joint Positive Train Control Project
    Polivka, Alan ;
    Ede, Bill Moore
    2009-04-01 | PDF
    Positive train control (PTC) offers the promise of significant potential benefits in railroad safety, capacity, and efficiency. However, PTC reveals new and much more complex design issues than those encountered with conventional train control systems. This is largely because a PTC system comprises a large, distributed, real-time communications, co ...
  • Success Factors in the Reduction of HighwayRail Grade Crossing Incidents from 1994 to 2003
    Success Factors in the Reduction of Highway-Rail Grade Crossing Incidents from 1994 to 2003
    Horton, Suzanne ;
    Carroll, Anya
    2009-04-01 | PDF
    Between the years 1994 and 2003, incidents at highway-rail grade crossings declined by 41.2 percent. The reasons for this decline were unknown. The John A. Volpe National Transportation Systems Center was tasked by the Federal Railroad Administration to identify the salient success factors in highway-rail grade crossing incident reduction. The succ ...

    Modeling material failure during cab car end frame impact
    Stringfellow, Richard G. ;
    Paetsch, Christopher
    2009-03-03 | PDF
    New standards have been proposed to increase the strength requirements for cab car end structures and impose further requirements on their ability to absorb energy during a grade-crossing collision. This conference paper reports on a set of full-scales tests completed by Federal Railroad Administration (FRA) and the Volpe Center to assess the quasi ...
