With the CAMEROV® HHD-E®© system, we measure the height, the stagger and the superelevation of the rail with the catenary system directly on a manual ruler, using a hi-rail vehicle or other maintenance type of vehicle with 4 axles. This system can also be mounted directly on the vehicle for the rail maintenance. A new option is possible when it’s mounted; the measurement of the track gauge with two lasers.
