Small-scale measuring car for railway track geometry

MMD is a small-scale measuring vehicle for track geometry. Maximum measuring speed is 40 kph. MMD measuring bogie is a self-standing system capable of track geometrical parameters measuring. It can be integrated to a measuring vehicle.

It is composed of 3 main parts: bogie mechanism, sensors, electronic equipment.

These parts are parts are placed on the vehicle: Measuring and evaluation unit (industrial computer with software),  • Printers for printing the results of track geometry quality evaluation

Measured quantities:

  • horizontal alignment of both rails
  • top of both rails
  • track gauge
  • change of gauge
  • cant
  • twist on selectable base
  • radius of the curve
  • distance run


Measuring speed: to 40 km/h

Measuring step: 25 cm
