A locomotive comprises a DC power bus, traction motors, batteries, and a charging source, but has no prime mover engine. Each traction motor includes armature and field windings connected in parallel across the DC power bus. The batteries provide power to the DC power bus when in a motoring mode, and receive power from the DC power bus when in a charging mode and a dynamic braking mode. The charging source is connected across the DC power bus to provide charging power to the batteries when in the charging mode. The traction motors also provide charging power to the batteries when in the dynamic braking mode. The power from the charging source is less than the power that would be provided by a prime mover engine. The charging source provides no power to the traction motors when in the charging mode.
