Chinese Train Control System
Encyclopedia
The Chinese Train Control System (CTCS) is a train control system used on railway lines in
People's Republic of China
. CTCS is similar to the European Train Control System
(ETCS).
It has two subsystems: ground subsystem and onboard subsystem. The ground subsystem includes responder, track circuit, wireless communication network (GSM-R
), and Radio Block Center (RBC). The onboard subsystem includes onboard devices and onboard wireless module.
CTCS has several levels:
Levels 2, 3, and 4 are back-compatible with lower levels.
Rail transport in the People's Republic of China
Rail transport is the most commonly used mode of long-distance transportation in the People's Republic of China. Almost all rail operations are handled by the Ministry of Railways, which is part of the State Council of the People's Republic of China...
