Simulation techniques are used to assess the dynamic interaction between overhead contact lines and pantographs, as part of the prediction of current collection quality. This document specifies functional requirements for the validation of such simulation methods to ensure confidence in, and mutual acceptance of the results of the simulations. This document deals with: - input and output parameters of the simulation; - comparison with line test measurements, and the characteristics of those line tests; - validation of pantograph models; - comparison between different simulation methods; - limits of application of validated methods to assessments of pantographs and overhead contact lines. This document applies to the current collection from an overhead contact line by pantographs mounted on railway vehicles. It does not apply to trolley bus systems.

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.
- Supporting regulatory compliance and interoperability assessments.
