Abstract

The present invention is directed to a power transfer system and method for utilizing the electrical power generated by a powered vehicle, such as a locomotive. The power transfer system comprises an electromotive machine configured to generate electrical energy on the powered vehicle and an electrical system located outboard from the powered vehicle, which is configured to receive electrical energy. Interface equipment is provided, which is electrically coupled to the electromotive machine and the electrical system, to transfer electrical energy from the electromotive machine to the electrical system.
