1. A hybrid energy locomotive system for use in connection with a train, the system comprising:

  • a locomotive having a plurality of locomotive wheels;

    a locomotive traction motor associated with one of the plurality of locomotive wheels, said locomotive traction motor having a first rotatable shaft mechanically coupled to the one of the plurality of locomotive wheels;

    an electric power source selectively supplying locomotive electric power to the locomotive traction motor, said locomotive traction motor being operable in response to the locomotive electric power to rotate the first rotatable shaft and to drive the one of the plurality of locomotive wheels, said locomotive traction motor further having a dynamic braking mode of operation wherein the locomotive traction motor generates electrical energy in the form of electricity; and

    an electrical energy capture system in electrical communication with the locomotive traction motor, said electrical energy capture system selectively storing electrical energy generated in the dynamic braking mode and selectively providing secondary electric power from said stored electrical energy, whereby the electrical energy capture system selectively supplements the locomotive electric power with the secondary electric power.
