System for scanning the environment from a moving train. The main component consists of two high speed spindles that deflect a measuring laser beam radially. During the ride of the train, a virtual tunnel is scanned in 3D. IDC, together with the customer, takes over the development, builds the prototypes and the special spindles required for the rough operating conditions.

IDC develops and builds its own internal profile grinding machine, which is unique in the world. Internal helical gears can be produced with complicated corrections and highest accuracy. The heart of the machine is the directly driven hollow shaft with a continuous inner diameter of 400mm.
