ABSTRACT:
The present invention relates to a train vehicle speed control apparatus which recognizes a change in one of the acceleration rate or the deceleration rate of a train moving along the track and the control of the train velocity in relation to what distance will be required for a desired operation of the train such as a predetermined decrease in the train speed or a stopping of the train. If the deceleration rate has changed, for example, the fixed physical system limits what control can be exercised and the velocity of the train can be modified to adjust the actual stopping distance used by the train or with a fixed stopping distance desired then the permitted train velocity can be changed.
