Conventional Automatic Train Protection (ATP)
With Trainguard, Siemens has created a modular system for conventional train control that can be deployed universally. The most important safety-relevant and operational functions relate to optimized headway times, punctuality and reliable track-to-train transmission.
Trainguard Zub 200 – intermittent automatic train control system
The intermittent automatic train control system Zub 200 can be integrated into existing signaling systems. Its modular design allows an optimum configuration for every line.
Zub 200 places no specific requirements on the signaling system in order for the railways to be protected, and it supports the driver with a host of automatic functions such as:
Continuous and reliable monitoring of speed and braking
Display of target and actual speed in the driver’s cab
Acoustic alarm if the target speed is exceeded, and automatic triggering of the brakes
Train stop at stop signals
Support of control systems by means of line data.
Trainguard LZB 700 M – continuous automatic train control system
The Trainguard LZB 700 M continuous automatic train control system is a high-performance system for automatic train protection (ATP) and automatic train operation (ATO). It optimizes both punctuality and headways. In addition, it saves work for the driver, who can focus more on passenger safety.
Trainguard LZB 700 M is a modular system especially suited for metros up to 160 km/h and light rail transits that need to increase traffic volume on existing lines with short headways. The Trainguard LZB 700 M equipment, for example, enables the present driving instructions to be displayed continuously in the driver’s cab and allows continuous monitoring of the train speed. Light signals can be dispensed with.
Trainguard Imu 100 – inductive transmission system
Trainguard 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 Trainguard Imu 100 trackside equipment are received by the on-board unit via the vehicle antennas.
