Railway applications - Compatibility between rolling stock and train detection systems - Part 1: General

This document describes a process to demonstrate compatibility between Rolling Stock (RST) and Train Detection Systems (TDS). It describes the characterization of train detection systems, rolling stock and traction power supply systems. It is worth noting that the demonstration of technical compatibility between the rolling stock and infrastructure with respect to physical dimensions is not detailed in this document. This document is not generally applicable to those combinations of rolling stock, traction power supply and train detection system which were accepted as compatible prior to the issue of this document. However, as far as is reasonably practicable, this document can be applied to modifications of rolling stock, traction power supply or train detection systems which may affect compatibility. The detailed process can be used where no rules and processes for compatibility are established.

Bahnanwendungen - Kompatibilität zwischen Fahrzeugen und Gleisfreimeldesystemen - Teil 1: Allgemeines

Applications ferroviaires - Compatibilité entre matériel roulant et systèmes de détection de train - Partie 1 : Généralités

La présente Norme européenne décrit une procédure permettant de démontrer la compatibilité entre le matériel roulant (MR) et les systèmes de détection de train (SDT) sur un itinéraire donné. Elle référence également les méthodes de mesure des courants et des champs magnétiques perturbateurs, les méthodes de mesure de la susceptibilité des systèmes de détection de train, ainsi que la caractérisation des alimentations de traction. La procédure décrite dans la présente norme s'applique également aux trains de grande ligne, aux véhicules légers et de type métro. Les paramètres fondamentaux de compatibilité concernant les grandes lignes sont couverts par le document Interface de l'ERA (ERA/ERTMS/033281). Il convient de noter que la présente norme ne couvre pas la démonstration de la compatibilité entre le matériel roulant et l'infrastructure en ce qui concerne les dimensions physiques. Selon la Directive d'interopérabilité, l'évaluation de la compatibilité comprend deux étapes. La première étape concerne l'autorisation de mise en service vis-à-vis des limites générales. La seconde étape concerne la mise en service, lorsque les limites spécifiques de compatibilité avec les SDT sont en dehors des limites générales ou que des SDT non interopérables ont été installés sur la ligne où le MR circulera. En dehors des trains de grande ligne ou des lignes isolées de types véhicule léger/métro, les exigences de compatibilité sont abordées dans une même étape d'autorisation. La présente Norme européenne ne s'applique généralement pas aux ensembles matériels roulants, alimentations de traction et systèmes de détection de train qui ont déjà été reconnus compatibles avant l'édition du présent document. Toutefois, la présente Norme européenne peut être appliquée, dans des limites raisonnables, aux modifications de matériels roulants, d'alimentations de traction et de systèmes de détection de train susceptibles d'affecter la compatibilité.

are established compatibility limits or not;
2) rules for characterization of train detection systems;

Introduction
This document defines a process to demonstrate compatibility between rolling stock operating on an area
of use or network and train detection systems installed in this area of use or network.
Currently, general rules for the maximum levels of interference allowed, and maximum susceptibility
levels (or minimum required immunity levels) are not established in every country. This is due
