A locomotive propulsion system onboard a locomotive platform includes a traction motor, a propulsion electrical storage device, an ancillary electrical storage device, and a controller. The propulsion electrical storage device is electrically connected to the traction motor via a propulsion circuit, and the ancillary electrical storage device is electrically connected to the traction motor via an ancillary circuit. The controller is configured to direct the ancillary electrical storage device to supply electric current to the traction motor via the ancillary circuit to power the traction motor during an elevated demand period. At an end of the elevated demand period, the controller is configured to control the ancillary circuit to stop conducting electric current from the ancillary electrical storage device and to direct the propulsion electrical storage device to supply electric current to the traction motor via the propulsion circuit to power the traction motor. 106 106A 106B 10 106C 108 201 Location 208 determining -228 22--d /0deic .\' IController H device 226 I/O device| | Processor(s) Sensor(s) - 224 2181---222 PESD AESD -206 P 214B L--- 214 -, --- 216B3 200,-_ TM 1 202A 202B- TM 2 210 211 211 212
