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; andautomatically controlling the train to travel according to the trip plan for the train mission using a controller disposed onboard the train. 2. The method of claim 1, wherein a total power of the power outputs from the first set of locomotives does not exceed the amount of power required for the trip mission. 3. The method of claim 1, further comprising modifying the trip plan to include addition of an incremental locomotive having a backup power in the train in addition to the first set of locomotives, wherein the incremental locomotive is configured to be switched out of an idle mode during movement of the train to provide the backup power in event of a failure of one or more locomotives in the first set of locomotives. 4. The method of claim 1, wherein the locomotives in the first set are selected based on at least one of a type of engine of one or more of the locomotives or a quantity of locomotives required to provide at least the amount of power required for the trip mission. 5. The method of claim 4, wherein said quantity of the first set of locomotives is a smallest quantity of locomotives from the group of locomotives having a total of the power outputs of the locomotives that is at least as large as the amount of power required for the trip mission. 6. The method of claim 1, wherein the first set of locomotives is selected such that the locomotives in the first set have a total of the power outputs that just meets the amount of power required for the train mission while yielding improved fuel efficiency for the train relative to selecting another set of the locomotives for inclusion in the train by reducing at least one of acceleration needs or braking needs of the train during the trip mission. 7. The method of claim 1, wherein the first set of locomotives is selected by selecting a minimum number of the locomotives having a total of the power outputs that just meet the amount of power required for the train mission while yielding improved fuel efficiency for the train relative to selecting another number of the locomotives for inclusion in the train such that, when the train is assembled and traveling along a track, one or more of the locomotives in the first set are able to be operated in a higher power setting and one or more other locomotives in the first set are able to be operated in at least one of a lower power setting, idle, unpowered standby, or an automatic engine start-stop mode during travel according to the trip mission while the locomotives that are included in the train are still able to provide the power outputs that just meet the amount of power required for the train mission. 8. The method of claim 1, wherein the power outputs of the locomotives are based on at least one of horse power ratings or starting tractive effort ratings of the locomotives. 9. The method of claim 1, wherein the amount of power required for the trip mission is based on at least one of a train load of the train or a trip mission time available for the trip mission. 10. The method of claim 9, wherein the train load is based on at least one of an engine configuration of one or more of the locomotives, a number of the one or more railcars in the train, a content of the one or more railcars, an age of the one or more railcars, or historical data related to a previous tip of the train according to the trip mission. 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. 12. The system of claim 11, wherein a total power of the power outputs from the first set of locomotives does not exceed the amount of power required for the trip mission. 13. The system of claim 11, wherein the one or more processors are configured to control the train to travel according to the trip plan with an additional incremental locomotive selected for inclusion into the train, the incremental locomotive having a backup power in the train in addition to the first set of locomotives and being configured to be switched out of an idle mode during movement of the train to provide the backup power in event of a failure of one or more locomotives in the first set of locomotives. 14. The system of claim 11, wherein the locomotives in the first set are selected for inclusion in the train based on at least one of a type of engine of one or more of the locomotives or a quantity of locomotives required to provide at least the amount of power required for the trip mission. 15. The system of claim 14, wherein the quantity of the first set of locomotives is a smallest quantity of locomotives from the group of locomotives having a total of the power outputs of the locomotives that is at least as large as the amount of power required for the mission. 16. The system of claim 11, wherein the first set of locomotives has a total of the power outputs that just meets the amount of power required for the train mission while yielding improved fuel efficiency for the train relative to selecting another set of locomotives for inclusion in the train by reducing at least one of acceleration needs or braking needs of the train during the trip mission. 17. The system of claim 11, wherein a minimum number of the locomotives having a total of the power outputs that just meet the amount of power required for the train mission is included in the first set while yielding improved fuel efficiency for the train relative to selecting another number of the locomotives for inclusion in the train such that, when the train is assembled and traveling along a track, one or more of the locomotives in the first set are able to be operated in a higher power setting while one or more other locomotives in the first set are able to be operated in at least one of a lower power setting, idle, unpowered standby, or an automatic engine start-stop mode during travel according to the trip mission while the locomotives that are included in the train are still able to provide the power outputs that just meet the amount of power required for the train mission. 18. The system of claim 11, wherein the power outputs of the locomotives are based on at least one of horse power ratings or starting tractive effort ratings of the locomotives. 19. The system of claim 11, further including a train load estimator that is configured to provide a train load of the train to the one or more processors and the one or more processors are configured to calculate the amount of power required for the trip mission based on the train load. 20. The system of claim 19, wherein the train load is based on at least one of an engine configuration of one or more of the locomotives, a number of the one or more railcars in the train, a content of the one or more railcars, an age of the one or more railcars, or historical data related to a previous trip of the train according to the trip mission. 21. The system of claim 11, further including a trip mission time estimator that is configured to provide a trip mission time that is available for the trip mission to the one or more processors and the one or more processors are configured to calculate the amount of power required for the trip mission based on the trip mission time. 22.
