Abstract

A train is connected to provide wired distribution power (WDP) using at least one standard locomotive consist. The train includes a first locomotive separated from a second locomotive by a plurality of cars; and a communication train line connected to the locomotive and cars and extending through the train. Each of the locomotives has a propulsion system, a propulsion controller to control the propulsion system in response to one of operator propulsion signal and multi-unit (MU) propulsion signal, and a MU communication line and connector for communicating control signals, including the MU propulsion signal, with an adjacent locomotive. At least the first locomotive is connected to the communication train line of an adjacent car by the multi-unit connector of the first locomotive to one of receive and transmit the MU propulsion signals via the communication train line.
