Track Geometry

The DTK Track Geometry measurement system logs the entire track geometry and track profiles for regular rail services.

Variables Captured:

  • Gauge
  • Groove width, groove depth or railhead height
  • Current contour of rails (wear)
  • Track cant
  • Twisting
  • Yaw angle
  • Ramps
  • Longitudinal level
  • Alignment
  • Curve radius
  • Shocks between wheel and rail
  • Smooth running of axle on the rails (loosening of rails)
  • Position on the route (GPS coordinates and route)
  • Speed

plus optionally:

  • Rail-wheel contact
  • Noise levels


Track geometry is obtained under load on standard passenger rolling stock of the relevant transport operator.

Even while still on the measurement journey, a first impression can be obtained of the platform geometry since the measurement data is displayed on our monitors.

After a second measurement the measurement campaigns can be compared to one another to determine changes in the track geometry or in the contours. This provides information on how the wear of the infrastructure has developed.


Our easy-to-use DTK evaluation software enables you to determine all deviations above and below the specified measurement tolerances.

To evaluate wear, for each chosen route position the current contour of the rails can be displayed and compared with the ideal contour.
