ABSTRACT:
A mobile track working machine comprises a machine frame, operating tools adjustably mounted on the machine frame, drives for adjusting the operating tools into various operating positions and into an inoperative position with respect to the track rails, controls for the drives for adjusting the operating tools into the various operating positions and into the inoperative position, and an apparatus for automatically controlling the positions of the operating tools. The apparatus includes sensors for monitoring the transverse position of the track rails and obstacles along the track, generators for output signals indicating respective ones of the monitored transverse position of the track rails and of obstacles along the track, and transmitters for transmitting the output signals to the drive controls whereby the operating tools are adjusted into the respective positions in response to the output signals.
