Two New Lines in Two Cities! Two New Lines Utilizes TST’s CBTC System!

At the beginning of the new year, Thales SEC Transport (TST) successfully won the bid for the signaling system integration projects of Changchun Rail Transit Line 9 (Airport Line) Phase-I construction as well as Qingdao Metro Line 8 branch.  



The main line of Changchun Rail Transit Line 9 Phase-I construction is 28.256km long, covering 8 stations. After the operation of Changchun Metro Line 9, it can effectively connect the urban area of Changchun, Lianhuashan Ecological Tourism Resort, Changchun New Area and Jiutai District, which is of great significance for promoting the development of the eastern urban area of Changchun and alleviating the pressure of passenger flow.



Qingdao Metro Line 8 branch is a key implementation project of Qingdao’s three-year urban renewal and construction action, as well as the first metro line in county-level cities of Shandong Province. The branch line starts from Dajian Station of Line 8 and ends at Jiaozhou Railway Station, covering 12 stations with a total length of 20.4 km.


Changchun Rail Transit Line 9 is the first subway line won by TST in Changchun. Qingdao Metro Line 8 is the fourth line won by TST in Qingdao. Both of them will be equipped with mature and reliable TSTCBTC® 2.0 signaling system independently developed by TST. The high availability and reliability performance characteristics of the 2.0 signaling system have been fully verified on Shanghai Line 5 (the first line in China to operate, renovate, and construct simultaneously), Shanghai Line 14 (the first GoA4 line in China to support reverse FAM), and Zhengzhou Line 6. The TSTCBTC® 2.0 signaling system adopts the “dual CBTC” redundancy system architecture independently innovated by TST, allowing for the operation with “zero interruption”. Additionally, the system adopts the integrated interlocking train control, enabling efficient turnbacks and shorter departure intervals, and greatly improving the operational efficiency of lines by leveraging the advantages of the “vehicle-based and operation-centered” moving block signaling system.


So far, TST’s CBTC system has covered 42 lines in 16 cities of China. TST will stick to the customer-oriented philosophy, providing customers with safe and leading technical solutions and full lifecycle operation and maintenance services, bringing a joyful travel experience to more cities.
