Abstract
A hybrid propulsion system for a locomotive is disclosed. The hybrid propulsion system comprises: ground engaging elements associated with the locomotive; a prime mover for powering propulsion of the ground engaging elements; a traction motor associated with the ground engaging elements; a battery associated with the traction motor; and a controller. The controller includes a route dataset having a topography of a route of the locomotive. The controller is configured to: analyze the topography of the route and location of the locomotive; identify when the locomotive enters a geofence area; and activate a boost mode to discharge an electric energy stored in the battery to the traction motor to boost a tractive force of the ground engaging elements.
