Beijing opens world’s longest CBTC metro line

The latest section of Beijing Subway’s Line 10 opened at the end of December 2012, and at 57km in length with more to follow is now claimed to be the world’s longest metro route equipped with Communications Based Train Control (CBTC) signalling.

Line 10 forms part of the outer subway loop linking the North West and South East of the city centre, and the first sections opened in 2010. The second section of the route comprises 30km of track and has 21 stations – with the final third section expected to be completed in Spring this year.

Siemens’ popular Trainguard MT forms the CBTC system using moving block signalling to optimise route capacity and speed. Siemens has scored significant success in China, with installations in operation in cities such as Guangzhou and Nanjing in addition to the country’s capital.
