Axle counters are vital train detection equipment which is a one-to-one alternative to track circuits. Unlike track circuits, their functioning does not depend on the ballast resistance of the track.
The axle counter Az LM (FieldTrac 6315) is a 2-out-of-2 multiple section axle counter based on a microprocessor configuration. For applications in Thales interlockings a 2-out-of-3 version is also available. It simultaneously can evaluate up to 32 detection points (Zp30H) and monitor up to 32 sections independently of the state of the track and of the section length.
