Siemens will provide its Trainguard MT automatic train control system, Trackguard Sicas ECC electronic interlockings, and Airlink radio transmission system. Siemens says the system transfers data continuously between the metro line and the train via the radio transmission system, while Trainguard MT uses less trackside equipment than conventional train protection systems. Commissioning of the 13-station extension is planned for 2016.
The extension of Line 2 will connect Suzhou's eastern suburbs with the city's metro network. The existing 27km north-south Line 2 has 22 stations and its northern terminus is the Suzhou North station, the city's primary railway hub, which provides direct high-speed links to Shanghai and Beijing.
