A cooling system includes a cooling loop containing a cooling fluid configured for circulation through an engine, an auxiliary alternator configured to be driven by the engine for powering auxiliary loads of the rail vehicle, and a canned pump positioned within the cooling loop and being configured to circulate the cooling fluid through the cooling loop. The canned pump includes an integrated induction motor for driving the pump. The system further includes an electronic control system electrically connected to the auxiliary alternator and configured to electrically power the induction motor of the canned pump independently of a mechanical output of the engine.
