Abstract
An improved automatic control system for a train of transit vehicles which regulates the velocity of the train and its braking rate in accordance with a predetermined velocity/distance profile. The system includes apparatus for compensating for variations in wheel diameter and train length in such a manner as to assure that the center of the train regularly stops at a predetermined point with respect to a desired station stopping point. On board receivers are responsive to wayside signal devices for establishing the operating velocity of the vehicle and for initiating entry into the predetermined braking profile. Since vehicle control is effected by wayside signal devices, the distance between stopping points may be indefinite. The system includes apparatus which permits passing selected stopping points when desired.
