US 2026/0175884 A1 · PREPLANNED LOCOMOTIVE COMMUNICATIONS LOSS MANAGEMENT

Abstract

Operating one or more locomotives of a train consist when communications to the one or more locomotives are lost depriving the locomotives of receiving real-time operating commands in an autonomous or semi-autonomous operating environment is provided. An energy management system generates real-time operating commands including throttle and brake settings for the train consist locomotives for operating the locomotives when communications to the locomotives are operating. Preplanned operating commands are generated for the train consist locomotives to set throttle and brake settings for the locomotives when communications to a lead train consist locomotive or between the lead train consist locomotive and remote or trailing train consist locomotives are lost. After communications are restored, the energy management system automatically switches from the preplanned operating commands back to real-time operating commands.
