Abstract
A system includes one or more processors and memory storing processor-executable instructions that cause the one or more processors to perform operations. The operations include generating a driving strategy for a traveling route of a train based on saved data in the system, the train comprising at least one diesel-electric locomotive (DEL) and at least one battery-electric locomotive (BEL); operating the train according to the driving strategy; receiving update data; revising the driving strategy based on the saved data and the update data including: determining an amount of energy for the train to traverse a segment of the traveling route based on the driving strategy and the update data, and determining a distribution of the amount of energy between the at least one DEL and the at least one BEL based on the driving strategy and the update data; and operating the train according to the revised driving strategy.
