Abstract
A system to determine the instantaneous position of a vehicle (11) which is attached to a track (12) by a mast arm (13) includes sensors (17, 19) to determine the location of the point (A) at which the arm (13) is attached to the track (12). An additional sensor (32) provides a signal to a circuit (47) which also receives signals from sensors (17, 19) and then locates the lateral and longitudinal position of the vehicle (11) with respect to point (A). Once the instantaneous position of the vehicle (11) has been established, a signal representative thereof is compared with a reference signal and the vehicle is controlled accordingly.
