ABSTRACT:
A train separation detector for a distributed power control system in railroad trains uses the distance traveled input from an axle drive generator or similar device to compute the speed of the lead locomotive and the speed of the remote locomotives and also the distance traveled by the lead locomotive and the remote locomotives per unit of time. Normally, both the distance traveled and the speed of the lead and remote locomotives will, on average, be the same since they are in the same train. If there is a separation, however, both the distance traveled and the speed of the lead and remote locomotives will be different to the extent that there is a train separation. By comparing the speed and distance traveled of the lead and remote locomotives, the distributed power system will be able to detect train separation and take appropriate action.
