Abstract
Abstract Track alignment deviations are measured with three measuring gears having an axle biased into engagement with a respective track rail and moving transversely in response to alignment deviations. A measuring device is movably mounted on the chassis between the end measuring gears, and an independent transmission between the end measuring axles and the measuring device transmits the transverse movement to the respective end axle to the device. The combination of the transverse movements of the two end measuring axles and of the center measuring axle moves the measuring device between the end reference points a distance corresponding to the ordinate at the center measuring point, this movement generating a proportional signal which is transmitted to an indicator or recorder.
