Graw TEP Trolley - Measurement of track geometry

The trolley is designed for measurements of track geometry. The gauge readings are recorded automatically in its electronic memory in real time as the trolley travels along the track.

The operator can see measured values of the track gauge, cant, and the actual mileage on the display during measurements. The large size foil keyboard makes it possible to enter information on the track faults discovered and events noted. One can mark location, e.g., of the broken weld or rail, need to replace the sleeper or missing bolts.

TEP trolley has all features of TEC/TET trolleys and, moreover it can be used to:

  • measure and save transverse rail profiles every 0.5 m
  • display rail profile during the measurement
  • measure rail profile with accuracy of ± 0.3 mm
  • determine rail wear parameters with accuracy of ± 0.3 mm
  • make automatic assessment of rail profile in the track
