Automatic Train Control

Automatic train control systems continuously monitor all train movements and provide fail-safe signaling. In train operation with a driver, the train control system supports the driver with safety-relevant and operational functions. In driverless train operation, the train control system replaces the driver for maximum efficiency.

Trainguard MT CBTC – Automatic Train Control System

The modular train control system Trainguard MT CBTC provides the signaling basis for attractive, reliable, and efficient mass-transit systems. The radio-based system allows a choice between fixed or moving block operation and achieves headways of 90 seconds. Trainguard MT CBTC includes functions for monitoring, implementation and control of the entire operating sequence. It can be implemented in different degrees of automation such as semiautomatic operation, operation under driver control, and driverless operation.

Trainguard MT CBTC is based on tried-and-tested automatic train control solutions such as Canarsie CBTC, which demonstrate Siemens’ expertise in the field of radio-based train control and brown field environment. Thanks to standardized interfaces, Trainguard MT CBTC is compatible with various different operation control systems, interlocking designs and track-vacancy detection systems.


Airlink – CBTC

Airlink CBTC is a radio-based data communications system providing a continuous high-capacity, bidirectional link between the trains and the wayside. It is specifically designed to meet the needs of a CBTC application and to fulfill the requirements of an urban rapid transit environment. Airlink CBTC is a proven, highly reliable and cost effective radio solution that perfectly fits our Trainguard MT CBTC system.


Imu 100 – Inductive Transmission System

Imu 100 is an information-transmission system of modular design. It is used for transmitting information from the vehicle to the track and from the track to the vehicle. The data is transmitted in the form of telegrams at a speed of 50 kBaud using time-division multiplex.

Telegrams transmitted from the vehicle are received by trackside receiver antennas or loops and then processed by evaluation equipment. Telegrams sent from the Imu 100 trackside equipment are received by the on-board unit via the vehicle antennas.


Digiloc – Transponder Location System

The function of the Digiloc transponder location system is to supply trains with safety-relevant information about the train’s location. The location is determined at the moment the vehicle passes over a balise with local information. Information transmission is based on the magnetic coupling of a trackside balise and an on-board antenna.

Power is fed remotely to the transponders, and they require no interface with the other trackside equipment. Digiloc is particularly suitable for metro applications.

Compact Train Stop/Magnetic Transmission (CTS/M)

Train stops provide safe brake application in the event of a train passing a stop signal. The CTS/M train protection system consists of on-board equipment and wayside equipment and guarantees secure braking when a signal showing stop is passed. The system is based on conventional, magnetic transmission. The on-board equipment contains the operator control unit, an on-board unit as well as the vehicle magnet. The wayside components are track magnets.
