Trainguard MT

High-performing CBTC system

Siemens Mobility’s intelligent, future-oriented CBTC system keeps cities on the move and on time. You can count on 100% punctuality with Trainguard MT, which features our innovative Airlink radio communication system. Airlink provides secure, reliable connectivity between trains and the wayside infrastructure for continuous and smooth operation. Airlink also ensures highly efficient train operation and supports all levels of automation, from semi-automated to fully automated. As automation increases, the responsibility for operations management gradually shifts from drivers and operators to the system itself. The results are greater flexibility, performance, reliability, and maintainability.
