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.

  • Effect of Track Parameters on Rail Joint Bar Stresses and Crack Growth
    Effect of Track Parameters on Rail Joint Bar Stresses and Crack Growth
    Akhtar, Muhammad ;
    Davis, David
    2011-02-03 | PDF
    By their very nature, rail joints create discontinuities in the running surface of the rails. In addition to bending, thermal, and residual stresses, rail joints are also subjected to dynamic loads due to these discontinuities. Under normal track and load conditions, joint bars fail due to high cycle fatigue, which is evident from fatigue striation ...
  • Measurement and Estimation of Sleep in Railroad Worker Employees Research Results
    Measurement and Estimation of Sleep in Railroad Worker Employees [Research Results]
    United States. Department of Transportation. Federal Railroad Administration
    2011-02-01 | PDF
    Fatigue risk management systems provide a means to plan for and manage fatigue in round-the-clock operations such as railroading. Biomathematical fatigue models predict opportunities for sleep associated with a work schedule. The accuracy of the predictions depends, in part, upon the accuracy of the sleep estimation. The purpose of this study was t ...

  • Automated Measurement of Stress in Continuous Welded Rail
    Automated Measurement of Stress in Continuous Welded Rail
    Fateh, Mahmood
    2010-12-01 | PDF
    Most modern railways use continuous welded rail (CWR). A major problem in CWR is the almost total absence of expansion joints to accommodate seasonal thermal changes. This lack of joints results in derailments because of so-called sun kinks or buckling in hot weather (Figure 1) and breakage or pull-apart in cold weather. A related critical paramete ...
  • Guidelines for the specification of blue safety flags in railroad operations
    Guidelines for the specification of blue safety flags in railroad operations
    Hannon, Daniel J.
    ORCID ICON IMG
    2010-12-01 | PDF
    Blue flag protection in the railroad industry provides safety to workers from the inadvertent movement of equipment on which theyare working. Current Federal regulations provide minimum specifications for the devices that can be used as blue flags, allowingmany devices to be used as long as they are blue. Safety standards developed by national and ...
