General Information

Overview
EN 50318:2018/A1:2022 (CLC) defines functional requirements for the validation of simulation methods used to assess the dynamic interaction between pantographs and overhead contact lines (OCL). The standard supports reliable prediction of current collection quality by specifying what simulation inputs, outputs and validation evidence are required so simulation results can be trusted and mutually accepted. It applies to pantographs mounted on railway vehicles (not trolley buses) and updates the original EN 50318:2018 by amendment A1 (approved 2022).
Key topics and requirements
- Scope of validation: Requirements for validating simulation tools that predict pantograph–overhead contact line interaction and contact forces.
- Input / output parameters: Defines essential simulation inputs (geometry, span lengths, mechanical and electrical properties) and required outputs such as time histories of contact wire vertical position and pantograph displacement.
- Model types: Guidance for different model classes - lumped mass–spring–damper models and multi‑body models - including required stiffness and damping characteristics and handling of nonlinearities.
- Pantograph model validation: Criteria for validating pantograph models versus laboratory and line test measurements; includes exclusion of frequencies with measured apparent mass below 2 kg when calculating certain quality metrics.
- Line test comparison: Requirements for comparison between simulation results and measured line test data, plus characteristics of those line tests and how to use them for model validation.
- Inter-method comparison and limits: Procedures for comparing different simulation methods and explicit statements on the limits of applicability of validated methods for assessing pantographs and OCL.
- Practical considerations: Aerodynamic effects shall be considered at least by adjusting mean contact force as a function of speed; simulation results shall be frequency‑domain filtered using defined cut‑off frequencies.
- Terminology and references: Updates to terms/definitions (e.g., transfer function of a pantograph, wave propagation velocity) and normative references (e.g., EN 50119:2020, EN 50367:2020).
Applications and users
This standard is intended for:
- Rolling‑stock designers and pantograph manufacturers using simulation for design and verification.
- OCL designers and infrastructure managers validating contact line performance.
- Simulation software developers and test laboratories performing model validation.
- Certification and conformity assessment bodies and experts supporting TSI/ENE and LOC&PAS interoperability assessments.
Typical uses:
- Validating simulation tools before predicting current collection performance.
- Demonstrating compatibility between pantograph designs and overhead contact line systems.

Le document standard SIST EN 50318:2019/A1:2022 se révèle essentiel dans le domaine des applications ferroviaires, plus précisément en matière de systèmes de collecte de courant. Il vise à valider les simulations des interactions dynamiques entre les pantographes et les lignes de contact aérien, ce qui est crucial pour assurer la qualité de la collecte de courant. Parmi ses points forts, ce standard établit des exigences fonctionnelles claires pour la validation des méthodes de simulation. Cela permet d’assurer la confiance dans les résultats des simulations et leur acceptation mutuelle par les parties prenantes. Ce processus de validation est primordial pour garantir que les simulations reflètent fidèlement les conditions réelles rencontrées lors de l’exploitation ferroviaire. Le champ d'application de cette norme est bien défini. Il traite des paramètres d'entrée et de sortie de la simulation, ainsi que de la nécessité de comparer ces résultats avec des mesures effectuées lors de tests en ligne. Cela garantit que les modèles de pantographe validés sont représentatifs des performances réelles sur le terrain. De plus, le document compare différentes méthodes de simulation, ce qui permet de cerner les meilleures pratiques et d'optimiser les procédures d'évaluation. La pertinence de cette norme est également accentuée par ses limites d'application clairement énoncées, qui précisent que le standard concerne uniquement la collecte de courant à partir de lignes de contact aérien par des pantographes montés sur des véhicules ferroviaires. Cette précision évite toute ambiguïté en excluant les systèmes de trolley bus, rendant ainsi le standard spécifique et adapté aux besoins du secteur ferroviaire. En somme, le SIST EN 50318:2019/A1:2022 représente une avancée significative dans l’harmonisation des méthodes de validation des simulations d'interactions dynamiques entre pantographes et lignes de contact. Sa portée, ses points forts et sa pertinence en font un document incontournable pour les professionnels du secteur ferroviaire qui s'intéressent à la collecte de courant et à l'évaluation de la performance des systèmes de courant.

Ein weiterer wichtiger Aspekt ist die Validierung von Pantografenmodellen, die es ermöglicht, realistischere Simulationsergebnisse zu erzielen. Zudem behandelt die Norm den Vergleich zwischen verschiedenen Simulationsmethoden, was zur Identifizierung der besten Praxen in der Industrie beiträgt. Gleichzeitig werden die Grenzen der Anwendung der validierten Methoden klar umrissen, sodass Missverständnisse und Fehlerquellen bei der Bewertung von Pantographen und Oberleitungsanlagen minimiert werden. Die Norm ist speziell auf die Stromabnahme von Oberleitungsanlagen durch Pantografen, die an Schienenfahrzeugen montiert sind, ausgerichtet. Somit stellt sie eine wesentliche Ressource für Fachleute dar, die im Bereich der Bahntechnologie tätig sind und sicherstellen müssen, dass die Systeme effizient und zuverlässig funktionieren. Sie schließt explizit Trolleybus-Systeme aus, wodurch ihre Relevanz auf das Schienennetz концентriert ist und die spezifischen Bedürfnisse dieser Technologie präzise adressiert werden. Insgesamt stellt die SIST EN 50318:2019/A1:2022 eine wertvolle Anleitung zur Verfügung, um die Qualität der Stromabnahme in Schienenfahrzeugen zu evaluieren und zu optimieren. Sie fördert nicht nur technische Standards, sondern auch eine sichere und verlässliche Leitungsinfrastruktur im gesamten Bahnsystem.
