Control & signaling system
Our systems are certified to SIL4, the highest safety level in railway engineering, and always deliver fail-safe signals that clearly indicate whether a section of track is free or occupied. With robust wheel sensors mounted directly on the rails, every wheel passage is recorded. The sensors divide the track into sections and send pulses to an intelligent evaluation unit that counts the axles as the train passes in and out of the section. The result is automatically compared and directly determines the status of the track.

An axle counter or wheel sensor is a safety system in railway infrastructure used to determine whether a particular stretch of track is free or occupied by a train. The system works through sensors mounted on the rails that detect each passing wheel. Each wheel gives a signal (an impulse) and, as train wheels are mounted in pairs on axles, these impulses count as axles.
When a train enters a track section, the system counts how many axles pass in. When the train leaves the section, the axles are counted out again. An evaluation unit compares the number of axles in and out to determine when the next train can be allowed to enter the track.
Axle counters are often used as part of safety systems in rail networks with
