Protran Technology’s RailLife Forecasting Model (RailLife) is an analytic tool for helping a railroad determine when rail will require replacement based on failure/degradation history and predefined safety/maintenance thresholds. RailLife utilizes statistical and empirical techniques for determining rail degradation based on actual inspection information.


  • Forecasts when rail will need replacement
  • Determines degradation based on actual inspection information
  • Identifies location of track with accelerated degradation
  • Prioritizes rail maintenance
  • A forecast replacement date can be determined for each rail segment


  • Forecasts based on historical degradation and predefined safety / maintenance thresholds
  • Applies multivariate regression techniques for rail wear analysis
  • Uses hierarchy of techniques to determine the controlling failure mechanism and rate of degradation
