The Trimble Access Track Gauge Survey application in combination with a mechanical track measurement bar, Trimble control unit and Trimble total station is used for geodetic track surveying tasks.

With a Trimble S-series total station and the mechanical track measurement bar, track profiles are measured with millimeter precision at the desired positions. This solution is particularly suitable for smaller projects with only a few track sections to be measured.

 

 

Trimble Access Track Gauge Survey

  • Software module integrated in Trimble Access for optimized acquisition of track parameters
  • Determination of coordinates of the track axis, the left and right rail as well as the track gauge and cant (superelevation) with a mechanical track bar or a rail shoe
  • Measurement on the prisms of the movable or fixed track measuring bar in a constant or alternating measurement sequence
  • Export format for the directly measured track geometry
  • Interface to the Rail module of the Trimble 4D Control software for automatic track monitoring purposes
  • For all Windows Trimble Access control units and Android Trimble Access control unit Trimble TSC5
