The present disclosure relates to an automatic train operation system in railway vehicles, the system including: a speed profile generation unit configured to generate speed profile information based on limited speed profile inputted from outside; a track database stored with track gradient information and track curvature information for each track segment; a train speed controller configured to control a speed of the train using a current position, a current speed and the speed profile information of the train inputted from outside; and a propulsion system fault diagnosis unit configured to diagnose a fault status of the propulsion system based on the current speed of the train, the track gradient information, the track curvature information and propulsion notch information inputted from the train speed controller, and to calculate a performance depreciation ratio when the propulsion system is faulted and to provide the performance depreciation ratio to the train speed controller.
