PURPOSE: A train operation control system is provided to obtain information about a station by including a bidirectional TWC communication unit which communicates between a train and the station. CONSTITUTION: An onboard control unit(110) controls an operation of a train(10) at a station. A ground control unit(120) receives a control signal about a train stop and a door open from the train. A bidirectional TWC communication unit(130) includes a ground TWC communication unit(131) and an onboard communication unit(132). The ground TWC communication unit receives information from the train and transmits the information to the ground control unit. An integrated control board(180) controls the operation of various operation apparatuses at the station by including a screen door system(190).
