Abstract
An interface system including locomotive and car electrical trainline terminals, locomotive and car brake pipe ports and a locomotive pressure supply port. A train brake pipe valve controls pressure on the train brake pipe port. A controller monitors pressure on the locomotive brake pipe port and controls the train brake pipe valve in response to pressure on the locomotive brake pipe port. The controller also provides ECP commands on the train electrical terminal in response to pressure on the locomotive brake pipe port and provides electrical power on the train terminal from the locomotive electrical trainline terminal. The car electrical terminal is connected to the ECP trainline for providing ECP commands and power to the ECP equipped train devices. The controller may also control an emergency valve to produce an emergency on the locomotive brake pipe port. A transition valve on the brake pipe port allows bi-directional connection of the interface system.
