Intermittent Automatic Train Control for reliable railway safety
Stadler develops and produces train control systems for reliable railway safety. This includes both the fully automated train control system Stadler NOVA Pro and the Intermittent Automatic Train Control. Our tried-and-tested systems ensure precise train control and safety in urban rail transport. Stadler's train protection technology is based on the latest standards and ensures precise train tracking and control.
Our Intermittent Automatic Train Control are designed to maintain safe distances between trains, regulate speeds and prevent collisions. They offer seamless integration into existing infrastructures and ensure safe train routing while taking track conditions and signalling into account.
Stadler develops train protection systems for trackside and on-board communication that meet the highest safety requirements and increase the efficiency of rail transport. Our train protection systems are the cornerstone for safe and efficient monitoring of rail traffic.
PZB222 Intermittent Automatic Train Control
The PZB222 Intermittent Automatic Train Control can prevent hazards caused by the driver ignoring or incorrectly recognising signals or exceeding the speed limit. The PZB222 vehicle equipment can be supplied as SIL3 or SIL4 depending on the selected maintenance intervals. It is also compatible with systems from other manufacturers. The integrated IMU function for data transmission from the vehicle to the track enables the track-side localisation of vehicles for route requests and the transmission of vehicle-specific data.
PZB600 M/I Intermittent Automatic Train Control
PZB600 Intermittent Automatic Train Control is used in the rail network to realise a forced dependency between a signalled stop command and safe braking of the train. The PZB600 M (magnetic) and PZB600 I (inductive) systems developed by Stadler are such point-type devices, which are typically used as automatic train stops. If a stop signal is crossed, the train is automatically forced to brake.
PZB600 systems are typically used as part of traffic signalling systems and electronic interlockings in urban traffic to prevent trains from passing signals that indicate a stop in the "train protection" operating mode. However, they can also be used as elements of speed monitoring devices: If the monitored vehicle exceeds the maximum permitted speed at the monitoring points, the speed interlock is activated and causes the vehicle to be forced to brake.
IMU 91 frequency decoder systems
Stadler offers IMU 91 frequency decoder systems for the transmission and corresponding information evaluation for serial inductive message transmission.
Two variants are available: If only a presence detection is to be transmitted from the vehicle to the track, transmission of the pure carrier frequency 91 kHz is sufficient. If, on the other hand, additional vehicle information is required, several audio frequencies can be modulated onto the carrier frequency. This information can include, for example, the line, course and destination of the vehicle.
Communication from the track to the vehicle is also possible. This retransmission is also based on IMU amplitude modulation. The system can be operated as a stand-alone solution or integrated as a subsystem in more complex control systems and installations.
