Abstract: In one embodiment, a multi-engine locomotive includes at least one converter to convert mechanical energy outputted by the engines to Direct Current (DC) electrical energy, a traction motor, and a DC bus connected to the engines, converter, and traction motor. The engines are configured to provide a power-per-length and/or power density that is greater than the power-per-length and/or power density of a single-engine locomotive having a power rating approximately the same as the cumulative power rating of the engines in the multi-engine locomotive.

Abstract: The present invention is directed to a locomotive comprising energy storage units, such as batteries, a prime energy source, such as a diesel engine, and an energy conversion device, such as a generator. The locomotive comprises one or more of the following features: a separate chopper circuit for each traction motor and a controller operable to control separately and independently each axle/traction motor.

Abstract: The present invention is directed to a locomotive that includes: (a) a transmission (105) operable to drive a plurality of axles; (b) an electric motor (104) operatively connected to and driving the transmission; (c) an energy storage unit (106) operable to store electrical energy and supply electrical energy to the electric motor; (d) one or more prime movers (102) operable to supply electrical energy to the energy storage unit and electric motor; and (e) a power distribution bus (109) electrically connecting the energy storage unit, prime mover(s), and electric motor. The energy storage unit and/or generator provide electrical energy to the electric motor via the power distribution bus to cause the electric motor to rotate the axles via the transmission.

Abstract: The present invention is directed to applying various control options for selecting the number of operating power sources for a multi-power source vehicle comprised of a number of prime power sources and, optionally including energy storage systems. The invention is applicable to large vehicles such as locomotives, mining trucks, tugboats and large cranes. The present invention is directed specifically at providing selectable operating modes for different locomotive speed ranges and work loads. The invention is based on a common DC bus electrical architecture so that prime power sources need not be synchronized. The invention includes multiple- engine locomotives in which the engine systems may be electrically connected in parallel or in series or in combinations of parallel and series to a DC bus.
