1. A locomotive, comprising:
- a transmission operable to drive a plurality of axles, each axle being connected to at least one wheel;
an electric motor operatively connected to and driving the transmission;
an energy storage unit operable to store electrical energy and supply electrical energy to the electric motor;
one or more prime movers operable to supply electrical energy to the energy storage unit and electric motor; and
a power distribution bus electrically connecting the energy storage unit, one or more prime movers, and electric motor, whereby 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 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.
