AN INVESTIGATION OF FACTORS CONTRIBUTING TO WIDE GAGE ON TANGENT RAILROAD TRACK

Wide gage--a fatigue failure of the track to maintain the nominal lateral distance between rail heads--is one of several modes of track failure on which the AAR-FRA-RPI-TDA Track Train Dynamics Program has focused attention. To investigate the generation of wide gage on tangent track, experiments were conducted to measure track dynamic response and long-term fatigue life of track sections on the Union Pacific Railroad in Idaho. Results of these experiments have defined the important factors in this mode of track fatigue.
