A TRAIN OPERATION SUPPORT SYSTEM

A subject of the present invention is to implement smooth running of a train so that the train arrives at a station according to a specified timetable even if the train runs at a speed lower than a train performance curve. To solve the subject, a storage unit that stores a schedule train diagram of trains, minimum headway between a preceding train and a subsequent train, and a train performance curve of each train; and an operation processing unit that performs, when a delay arises in an operation of the trains, a process of determining a predicted departure time at which the subsequent train departs from a predetermined station and a predicted arrival time at which the subsequent train arrives at a next station of the predetermined station based on the schedule train diagram and the minimum headway, a process of determining a differential time between the predicted arrival time and the predicted departure time and correcting the train performance curve such that a running time becomes the differential time when the subsequent train runs following the train performance curve or an average speed when the subsequent train runs following the train performance curve becomes an average speed when the subsequent train runs between stations in the differential time, and a process of providing information about the train performance curve that has been corrected are included.
