Railway Applications - Technical parameters of train detection systems for the interoperability of the trans-European railway system Part 2: Axle counters
 N EN 50617-2

Annotation

This European Standard specifies parameters for the design and usage of axle counter systems.

For this, the standard 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 products.

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 Each parameter is defined by a short general description, the definition of the requirement, the relation to other standards and a procedure to show the fulfilment of the requirement as far as necessary. An overview on the safety relevance of each parameter is given – in the context of this European Standard – in a separate table.

This European Standard 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.

The frequency bands and rolling stock emission limits are currently defined in the axle counter FrM as specified in the CCS TSI Index 77.
