Abstract

See full text

A locomotive assembly including an auxiliary power unit and a method of providing auxiliary power to a locomotive are disclosed. The locomotive assembly includes a locomotive having a power bus, a primary power source electrically coupled to the power bus, and a locomotive controller programmed to control the primary power source and transmit a first command signal to a power unit that is electrically coupled to the power bus. The power unit includes an auxiliary engine-generator set, a power interface electrically coupling the auxiliary engine-generate set to the power bus, and an auxiliary controller electrically coupled to the locomotive controller. The auxiliary controller is programmed to receive the command signal from the locomotive controller indicating a desired amount of power, control the auxiliary engine-generator set to produce at least the desired amount of power, and control the power interface to deliver the desired amount of power to the power bus.
