Abstract

An energy storage car for a locomotive includes a hydraulic energy storage system designed to capture and reuse energy normally lost in dynamic braking. The energy storage car is preferably configured to provide functions sufficient to replace one of multiple locomotives used to pull a freight train. Braking and other methods for improved efficiency of such trains are provided.
