Abstract: A passenger locomotive is retrofitted with a hybrid energy head end power (HEP) system to generate head end power that is substantially continuously provided to a passenger railcar while the locomotive, which is operable in a motoring mode and a dynamic braking mode, is in use. The locomotive has a primary power source that provides primary electrical energy to a traction bus to power a traction motor when in the motoring mode. The traction motor generates excess electrical energy when in the dynamic braking mode. The HEP energy storage system generates head end power that is suitable for non-motoring use by a passenger railcar by converting the stored excess electrical energy and primary electrical energy into the head end power and providing the head end power to the HEP bus substantially continuously while the passenger locomotive is in use.

Abstract: A head end power system carried on a locomotive for a passenger train set that captures and stores excess electrical energy generated during dynamic braking of the locomotive. This excess electrical energy is converted to head end power for use on attached passenger railcars. Because passenger trains activate dynamic braking frequently, sufficient dynamic braking energy can be captured to supply a substantially continuous demand for head end power. In the event that the amount of captured energy is insufficient to meet demand, the head end power system may supplement the captured energy with energy generated by the primary power source on the locomotive.
