ABSTRACT:
A train separation detector for a distributed power control system in railroad trains and trains with an installed Electronic Control Pneumatic (ECP) brake system 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/or ECP brake system equipped cars and also the distance traveled by the lead locomotive and the remote locomotives and/or ECP brake system equipped cars per unit of time. Normally, both the distance traveled and the speed of the lead and remote locomotives and/or ECP brake system equipped cars 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 and/or ECP brake system equipped cars 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 and ECP brake system equipped cars, the lead locomotive will be able to detect train separation and take appropriate action.
