(Main)Railway applications - Technical parameters of train detection systems for the interoperability of the trans-European railway system - Part 2: Axle counters
Railway applications - Technical parameters of train detection systems for the interoperability of the trans-European railway system - Part 2: Axle counters
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 Interoperability Directive and the associated technical specification for interoperability relating to the control-command and signalling track-side subsystems.
The bands and rolling stock emission limits are currently defined in the Axle Counter FRM as specified in the CCS TSI Index 77.
Bahnanwendungen - Technische Parameter von Gleisfreimeldesystemen - Teil 2: Achszähler
Applications ferroviaires - Paramètres techniques des systèmes de détection des trains - Partie 2: Compteurs d'essieux
Le présent document spécifie les paramètres de conception et d'utilisation des systèmes de compteurs d’essieux.
Dans cette optique, il spécifie les paramètres techniques des systèmes de compteurs d’essieux associés aux limites de champ magnétique pour le matériel roulant (RST) dans le contexte de l'interopérabilité. En outre, des méthodes d'essai sont définies pour établir la conformité et les performances des détecteurs de compteurs d’essieux.
Les paramètres spécifiés sont structurés et affectés en fonction de leurs références de base suivantes:
— paramètres des systèmes de compteurs d’essieux ;
— paramètres basés sur le train ;
— paramètres basés sur la voie ;
— paramètres d'environnement et autres.
Chaque paramètre est défini par une courte description générale, la définition de l'exigence, la relation aux autres normes et une procédure pour montrer le respect de l'exigence autant que nécessaire. Pour chacun des paramètres, une vue d'ensemble de la pertinence relative à la sécurité est proposée dans un tableau à part, dans le cadre de le présent document.
Le présent document est destinée à être utilisée pour évaluer la conformité des systèmes de compteurs d’essieux et d'autres types de capteurs de roue utilisés pour la détection de train, dans le contexte de la Directive européenne sur l’interopérabilité du système ferroviaire transeuropéen et de la spécification technique associée pour l’interopérabilité traitant des sous-systèmes au sol ""contrôle-commande et signalisation".
Ce document peut également être utilisé pour les systèmes de compteur d'essieux installés sur des lignes qui ne sont pas déclarées interopérables (y compris les lignes de métro et de tramway).
Pour les capteurs et détecteurs de roues dans d'autres applications que les compteurs d'essieux, mais utilisant les mêmes capteurs sur le rail et les mêmes circuits de détection, les interférences transitoires et continues peuvent être considérées comme équivalentes aux détecteurs de compteurs d'essieux ou aux capteurs de compteurs d'essieux.
Les bandes de fréquence et les limites d'émission du matériel roulant sont actuellement définies dans la FrM relative aux compteurs d'essieux, telles que spécifiées dans le document ERA/ERTMS/033281.

Introduction
The working group SC9XA WGA4-2 has developed the limits for electromagnetic compatibility between rolling
stock and train detection systems, specifically track circuits and axle counter systems and correspondingly
published two technical specifications CLC/TS 50238-2 and CLC/TS 50238-3. These limits and associated
measurement methods are based on preferred existing systems (as defined in CLC/TS 50238-2 and
CLC/TS 50238-3) which are well established and still put forward for signalling renewals by infrastructure
managers.
To meet the requirements for compatibility between train detection systems and rolling stock in the future and
to achieve interoperability and free movement within the European Union, ERA/ERTMS/033281 defines the
relevant parameters for compatibility of rolling stock with track circuits and axle counter systems.
The train detection systems, track circuits and axle counters are an integral part of the CCS trackside subsystem
in the context of the Rail Interoperability Directive. The relevant technical parameters are enumerated in the
CCS and LOC&PAS TSI and ERA/ERTMS/033281. ERA/ERTMS/033281 specifies the parameters for rolling
stock relevant to compatibility with the infrastructure. This document covers all relevant technical parameters of
train detection systems (axle counter) in a manner that provides a presumption of conformity with interoperability
requirements, but is not limited to interoperable lines. This document refers whenever needed to
ERA/ERTMS/033281. Although the demand for FrM is driven by Interoperability requirements, it is independent
from the drive to introduce systems like ERTMS level 3 or level 2.
This document is based on the current understanding of the railway experts represented at WGA4-2 that track
circuits and axle counter systems will continue to be the essential two train detection systems for the foreseeable
future.
The published specification CLC/TS 50238-3 can be used to ascertain conformity of rolling stock with existing
individual wheel detectors.
In this document, the defined 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.
Where possible, the parameters as defined are consistent with other European Standards.
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 of the
safety relevance of each parameter is given – in the context of this document – in a separate table.

1 Scope
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.
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 document – in a separate table.
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.
This document can also be used for axle counter systems installed on lines which are not declared as
interoperable (including metro and tram lines).
For wheel sensors and wheel detectors in other applications than axle counters but utilizing the same sensors
on the rail and detection circuits, transient and continuous interference can be considered as equivalent to axle
counter detectors or axle counter sensors.
The frequency bands and rolling stock emission limits are currently defined in the axle counter FrM as specified
in the ERA/ERTMS/033281 document.
