  • Train control system
    Patent number: 5487516
    Abstract: A train control system includes an equipment for issuing, to a train under control based on a predetermined train schedule, an operational target to be attained in terms of the aimed position, aimed time and aimed speed. Once a target is issued, a possible run region of the train is determined, and another target may be set within the possible run region such that the train is not subjected to the ATC-based speed limitation or the like, thereby minimizing the cause of delay of the train operation.
