1. A method comprising:
- determining a trip plan for a train during a train mission, the trip plan designating one or more of speed settings or power settings of locomotives in a selected first set of the locomotives as a function of one or more of time during the train mission or distance along a route, the locomotives in the first set selected for inclusion in the train that is to travel according to the train mission, the locomotives in the first set associated with power outputs, wherein the first set of the locomotives include the power outputs that just meet an amount of power required for the train mission while yielding improved efficiency for the train to travel according to the one or more speed settings or power settings designated by the trip plan for the train mission relative to the train traveling using a different, second set of the locomotives in the train for the train mission; and
automatically controlling the train to travel according to the trip plan for the train mission using a controller disposed onboard the train.

Abstract
A method for determining the configuration of a diesel powered system having at least one diesel-fueled power generating unit, the method including a step for determining a minimum power required from the diesel powered system in order to accomplish a specified mission, and a step for determining an operating condition of the diesel-fueled power generating unit such that the minimum power requirement is satisfied while yielding at least one of lower fuel consumption and lower emissions for the diesel powered system.

11. A system comprising:
-
one or more processors configured to determine a trip plan for a train during a train mission, the trip plan designating one or more of speed settings or power settings of locomotives in a selected first set of the locomotives as a function of one or more of time during the train mission or distance along a route, wherein the first set of the locomotives include power outputs that just meet an amount of power required for a train mission while yielding improved efficiency for the train to travel according to the one or more speed settings or power settings designated by the trip plan for the train mission relative to the train traveling using a different, second set of the locomotives in the train for the train mission, wherein the one or more processors are configured to automatically control the train to travel according to the trip plan for the train mission. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
