The Chinese Train Control System (CTCS) is a signalling and control system aims for train protection and railway management. Claimed to be developed independently by China Academy of Railway Sciences, CTCS shares a lot of similarities with ETCS.
Values
CTCS Level 0
CTCS Level 0 follows the conventional trackside signalling system. Cab signalling may be installed, but only as a backup solution. IC-card based LKJ (Lieche Kongzhi Jianshi / Train operation supervision) system is used for record and supervise train operation. ATP may be implemented. Radio beacons may be installed.
While being rendered by train protection systems, CTCS-0 should be treated as a different train protection system from other levels of CTCS.
CTCS Level 1
Never implemented, use CTCS-0 instead.
Theoretically, CTCS Level 1 is for railroads with maximum speed between 120 to 160 km/h, however, the need for CTCS Level 1 decreased with the implementation of LKJ-15 system capable for higher speed.
CTCS Level 2
CTCS Level 2 is a cab signalling system, with trackside signailling not mandatory. Radio beacons pick up signal aspects from the trackside signals via signal adapters and telegram coders and transmit them to the vehicle as a movement authority together with route data at fixed points.
CTCS Level 3
CTCS Level 3 is a digital radio-based system. GSM-R was used in the beginning of development of Chinese HSR network, while LTE-M and NR-R are under testing.
CTCS Level 4
CTCS Level 4 (or CTCS-N) implements moving blocks with GNSS, as well as intergity self-check, leaving rail circuit only as backup.
Construction
Usage
railway:ctcs=* should be used on railway system in mainland China, as well as other railway systems equipped with Chinese management systems.
