Taking Baiyun International Airport North Turnback Station as an example, the process and operation mode of realizing the automatic change function of train number in the situation of turning back in or after the station are illustrated. It solves the problem that the signal cannot be cleared according to the plan due to the train number modifi cation error and the train number modifi cation delay caused by the dispatcher manually modifying the train number at the turnback station.
