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.
