MRail is the only system available on the market today that measures and records vertical rail deflection.  Using a laser/camera based system mounted onto a revenue generating car or inspection vehicle, MRail is able to measure the difference between the unloaded and loaded rail states.


  • Laser/camera based system mounted on truck (bogie) side frame
  • Fully autonomous operation
  • Data transmitted via onboard cell modem
  • Deflection data (YRel) can help identify areas of weak support cause from degradation of various sources (ties, joints, ballast, sub-ballast, etc.)
  • Deflection data (YRel) can be processed to help guide maintenance programs


  • Only available system on market that can measure vertical track deflection
  • Aids in the inspection of bridges and culverts
  • Complements other inspection methods to provide more complete track inspection
