• Abstract:
  This report was prepared as part of the Improved Track Structures Research Program ; managed by the Transportation Systems Center. This program is sponsored by the ; Office of Rail Safety Research, Improved Track Structures Research Division, of ; the Federal Railroad Administration. The report presents results from a parametric ; study of track response using a comprehensive track analysis model. Track response ; parameters include rail and tie bending moments, rail displacement, tie rail seat ; load, and the distribution of stresses in the ballast and subgrade. The effects of ; variations in tie sîze, tie spacing, ballast depth and rail fastener stiffness are ; presented in graphs suitable for track design trade-off studies. Alternative ; wood and concrete tie track configurations are evaluated using equivalent maintenance ; criteria. ; Maintenance criteria for track surface deterioration were reviewed to select ballast ; and subgrade stress parameters which can be related to track settlement rate for ; service loads. Formats for cumulative settlement criteria are evaluated using ; available laboratory data for the behavior of ballast and subgrade materials under ; repeated loads. Track lateral
