Trainguard MT is a versatile and modular system which can be individually tailored to the railway operator’s needs. Different train control and automation levels can be implemented, depending on the requirements for performance and functionality.

The Airlink access points distributed along the track are connected alternately to two independent central system routers (CSR) and overlap each other with their radio coverage. In this way, full radio coverage is maintained even if access points fail.

The central system routers are designed redundantly and serve, for example, a complete line of a metro system, including depot areas.

System overview The Airlink radio communication system guarantees a highly reliable seamless and redundant flow of information between the track and a train.

8 Secure, reliable connectivity between trains and the wayside infrastructure is a fundamental requirement in a CBTC system. Therefore, Siemens has developed the Airlink radio communication system to ensure continuous and smooth operation of its Trainguard MT automatic train control system. Airlink supports all levels of automation from semi-automated to fully automated train operation and ensures highly efficient train operation.

For this reason, the high-performance Trainguard MT system was chosen to ensure reliable and convenient passenger service.

After only a two-year project duration, Line 10 together with the Olympic Branch was opened to the public in July 2008 with a total length of 31 km. Today, these metro lines transport more than one million commuters per day and Line 10 has been extended to a ring line with a length of 56 km.
