ABSTRACT:
A remote radio railroad car located within or at the end of the train that charges or exhausts the brake pipe in response to radio commands from the lead unit. The brake pipe control system includes a first controller at a first car at the lead end for controlling the brake pipe at the first car and transmitting, via a radio link, brake pipe control signals to a second controller in a remote car in the train. The second controller controls the brake pipe at the remote car in response to the brake pipe control signals from the first controller. If the second controller is on the last car and the last car does not include an independent end of train device, the second controller transmits brake pipe condition signals to the first controller. If the second controller is on the last car and the last car does include an independent end of train device, the first controller established separate communication links with the second controller and the end of train device. If the second controller is not on the last car and the last car includes an end of train device, the first controller established separate communication links with the second controller and the end of train device.
