DIN EN 50617-2 VDE 0831-617-2:2025-09

This document specifies parameters for the design and usage of axle counter systems.
For this, this document specifies the technical parameters of axle counter systems associated with the magnetic field limits for RST in the context of interoperability. In addition, test methods are defined for establishing the conformity and the performance of axle counter detector.
The specified parameters are structured and allocated according to their basic references as follows:
— axle counter system parameters;
— train based parameters;
— track based parameters;
— environmental and other parameters.
This document is intended to be used to assess compliance of axle counter systems and other forms of wheel sensors used for train detection, in the context of the European Directive on the interoperability of the trans-European railway system and the associated technical specification for interoperability relating to the control-command and signalling track-side subsystems.
