Abstract

A locomotive assembly is provided. The locomotive assembly includes a locomotive having a power source configured to generate mechanical power. The locomotive also includes a generator configured to generate electrical power. The locomotive further includes an electric motor configured to provide motive power to the locomotive. The locomotive assembly also includes an auxiliary vehicle haying a power receiving device configured to receive electrical power from an external power grid. The auxiliary vehicle also includes a transformer and a circuit breaker. The circuit breaker and the transformer are configured to control the electrical power received by the power receiving device. The auxiliary vehicle further includes a cooling system configured to control a temperature of the transformer. The transformer is further electrically coupled to the electric motor of the locomotive to selectively provide electrical power to the locomotive.

First claim

What is claimed is:

1 . A locomotive assembly comprising:
a locomotive including:
a power source configured to generate mechanical power;
a generator mechanically coupled to the power source, the generator configured to generate electrical power: and
an electric motor electrically coupled to the generator, the electric motor configured to provide motive power to the locomotive; and
an auxiliary vehicle coupled to the locomotive, the auxiliary vehicle including:
a power receiving device configured to receive electrical power from an external power grid;
a transformer electrically coupled to the power receiving device and the electric motor of the locomotive, the transformer configured to selectively provide electrical power to the locomotive;
a circuit breaker electrically coupled to the power receiving device and the transformer, the circuit breaker and the transformer configured to control the electrical power received by the power receiving device; and
a cooling system fluidly coupled to the transformer, the cooling system configured to control a temperature of the transformer.

2 . The locomotive assembly of claim 1 further including an auxiliary fuel tank provided on the auxiliary vehicle and fluidly coupled to the power source, the auxiliary fuel tank configured to provide a supply of fuel to the power source.

3 . The locomotive assembly of claim 1 further including an auxiliary generator set provided on the auxiliary vehicle, the auxiliary generator set configured to provide an auxiliary electrical power to at least one of the locomotive and a plurality of wagons coupled to the locomotive assembly.
