Metro News: Guangzhou Metro develops new CBTC system

In cooperation with the China Railway Academy of Science and Technology, Guangzhou Metro has successfully developed a new CBTC signaling system which has now passed the scientific and technological achievement appraisal by Guangdong Province, China. This is an important achievement because the number of CBTC systems on offer is currently very limited.

The technical design of the MTC-I CBTC program was finished in 2008, experimental testing was finished in 2009, and field trials were conducted in 2010. Meanwhile, the CBTC system has received third party safety certification by Lloyds, and safety certification of related subsystems including computer-based interlocking system platform, trackside controller subsystem, on-board ATP subsystem, FIMI fail-safe intelligent input and output modules, axle counter (Safety Integrity Level 4) and ATS system(Safety Integrity Level 2). The system uses wireless communication based moving block technology. The achievement of scientific and technological identification and third-party safety certification has enabled the MTC-I CBTC signaling system to move into the engineering application stage.
