1. A hybrid energy railway vehicle system comprising:

  • a hybrid energy railway vehicle having a plurality of wheels;

    a traction motor coupled to at least one of the wheels, said traction motor having a motoring mode of operation for driving the coupled wheel and a dynamic braking mode of operation for braking the coupled wheel, and said traction motor generating dynamic braking electrical energy when operating in the dynamic braking mode;

    an electrical energy source for supplying charging electrical energy;

    an electrical energy storage system in electrical communication with the energy source and the traction motor for storing electrical energy, said energy storage system storing charging electrical energy supplied by the energy source to the energy storage system and storing dynamic braking electrical energy generated by the traction motor during braking, said energy storage system selectively supplying stored electrical energy to the traction motor for driving the coupled wheel;

    a control system controlling an operation of the hybrid energy railway vehicle, wherein the control system comprises;

    a computer readable medium having computer executable instructions for controlling the operation of the hybrid energy railway vehicle, said computer executable instructions defining a plurality of hybrid energy railway vehicle operating modes, each of said operating modes defining a set of operational parameters; and

    a processor configured to control the operation of the hybrid energy railway vehicle as a function of at least one of the operating modes.
