Abstract
A method of controlling the operation of a railroad train having a locomotive consist comprising one or more railroad locomotives to improve locomotive consist fuel efficiency, the method including calculating on-board the locomotive consist a load of the train being moved by the locomotive consist based on measuring the movement of the train in response to locomotive consist power settings, determining on-board the locomotive consist a current location of the train, identifying on-board the locomotive consist a change in condition of the track prior to the train reaching the change in track condition, and adjusting on-board the locomotive consist the locomotive consist power setting to optimize locomotive consist fuel consumption based on the calculated load of the train as the train is proximate to the change in track condition.
