DMA Power Rail Measurement System (PwRMS)

With the DMA Power Rail Measurement System, defects on the power rail track can be detected.

The Power Rail Measurement System is based on a non-contact optical measurement technology. It provides measurements of power rail gauge and height, evaluating its position relative to the running track a Rail Profile Measurement System is necessary.


  • Measurement of height and distance of the third rail from the track center.
  • Standard accuracy: ±1.0 mm
  • Number of cameras per rail: 1
  • Sampling rate: 300 profiles/second
