The requirements in railway construction are increasing continuously. Specifically, high speed tracks put very high demand on track geometry and therewith on track construction. A tamping machine requires exact information about the condition and position of the track ahead to make the required corrections and to work precisely and efficiently
The positioning errors of the track shall be measured with a mobile measuring unit. The measuring data shall then be used by the tamping machine.
ALIGNMENT OF THE ETCS-RADAR ON A LOCOMOTIVE
The Doppler-Radar which is measuring the exact speed of a train is an important part of the ETCS train control system in Europe. 2 such radars are mounted under each locomotive. To ensure a correct functioning, they must be precisely aligned.
Precise alignment and regular checking of the parallelity of the lower side of the radars to the rail.
