Railway applications - Credibility of simulations for virtual testing FprEN 17833

Publication date:   Jan 15, 2026

Scope

This document sets out a framework to assure simulation credibility for railway applications when complementing or replacing physical tests with virtual tests. This covers simulation model and tool verification and validation, input data and uncertainties, organization and processes of these simulations.
This document can be used particularly when simulations are not yet defined. Where applicable, this document can be used in conjunction with existing standards pertaining to the use of simulations.
If domain-specific standards mandate requirements for simulations, that are intended to replace or complement physical tests, this document is not meant to be applied and does not modify the requirements of those standards. However, this document could assist in future improvements and harmonization of domain-specific standards.
It does not provide domain-specific guidance on applying simulations.
For the use of technologies including, but not limited to, artificial intelligence, model-scale testing, and distributed computing, relevant potential technology-based risks can arise.
