Abstract
The present interface system includes a controller monitoring pressure on a locomotive brake pipe port, controlling pressure on a train brake pipe port in response to the pressure on a locomotive brake pipe port, providing ECP commands on an ECP trainline via a train electrical terminal in response to the pressure on the locomotive brake pipe port, and providing electrical power on the ECP trainline via an train electrical trainline terminal from the locomotive electrical trainline terminal. The system includes a three position change over valve. The system also includes a wireless display unit which communicates via a transceiver with the controller and displays information from the controller to the operator remote from the interface system.
