Train control system based on CBTC communication: With the rapid development of communication technology, especially radio technology, people began to study train operation control system based on communication technology. Its characteristic is to realize the two-way communication between the train and the ground equipment by using the communication medium, rather than the train operation control by using the track circuit as the medium.

The outstanding advantage of CBTC is that it can realize two-way communication between the train and the ground, with a large amount of information and fast transmission speed. It is easy to realize the mobile automatic block system, greatly reduce the laying of interval cables, reduce the one-time investment and daily maintenance workload, greatly improve the interval passing capacity, flexibly organize bidirectional operation and unidirectional continuous departure, and easily adapt to the train operation control with different speeds, different volumes and different traction types.
