Exactly positioned – efficiently check and document the position of overhead contact lines
The electrification of existing railway lines is progressing worldwide. New railroad tracks are being equipped as standard with overhead line systems supplying the moving trains with electricity. The overhead contact line has to be installed in a well-defined area with sufficient tension. Incorrect positioning can have fatal consequences. Therefore, the position of the contact wires must be checked at regular intervals with regard to their height and lateral position – if possible quickly and efficiently in regular operation.
