The CTCS-3 class automatic running vehicle-mounted device generates a corresponding control command according to the line allowable running speed information and the line gradient information. The train performs specific operations such as braking, which can effectively prevent the train from running automatically. In the event of an overspeed, the situation that threatens driving safety occurs. The information related to the operation of the platform correspondingly indicates that the door is located on the left or right side of the platform, and the location of the parking point of the corresponding channel.
