A power system housed in one or more modules or containers may be located as a unitary structure where desired, for example secured to a locomotive platform, allowing easy retrofits. A control subsystem may maintain an RPM of a prime mover at minimum that still provides an expected level of power from an electric machine for any one of a finite number of throttle settings. The control subsystem may dynamically adjust loads between various combinations of series and/or parallel couplings. A set of processor executable instructions may be configured for specific platforms by selecting appropriate set of values based on number of loads (e.g., driven axles), rating (e.g., horse power), other criteria (e.g., manufacturer, model, year). Characteristics may be determined and verified, and operation based on the outcome of such. A telematics system method logs and provides remote access to operational data, engine data, power system data, anti-idling overrides, unauthorized changes, and/or location.

The method of claim 6, further comprising: limiting a supply of power to the traction motors if the user-entered horse power rating is not within the defined threshold of the expected horse power rating of the locomotive platform. 10. The method of claim 6 wherein producing a notification if the user-entered horse power rating is not within the defined threshold of the expected horse power rating of the locomotive platform includes providing a message via at least one of a visual or an aural indicator and transmitting a message externally from the locomotive platform. 11.
