Railway applications - Testing and simulation for the acceptance of running characteristics of railway vehicles operated on the heavy rail network - Part 5: Calculations/Simulations

This document applies to all rail vehicles including OTM’s and Road-rail machines, which are operated on the heavy rail network with standard track gauge 1 435 mm and nominal static vertical wheelset forces up to 350 kN.
This document may also be applicable (partly or in full) to:
—    rail systems with different track layout, e.g. urban rail systems and/or,
—    rail systems with other than 1 435 mm nominal track gauge.
Note : For such rail systems other than 1 435 mm track gauge or urban rail systems, the related post analysis, limit values and test conditions could be different. They are specified nationally taking into account track design and operating conditions.
This document contains methods to replace tests specified in EN 14363-2, EN 14363-3 and EN 14363-4, completely or partly or to support the assessment of rail vehicles according to this document.

European foreword
This document (prEN 14363-5:2025) has been prepared by Technical Committee CEN/TC 256 “Railway
Applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document together with prEN 14363-1:2025, prEN 14363-2:2025, prEN 14363-3:2025, and
prEN 14363-4:2025 will supersede EN 14363:2016+A2:2022.
EN 14363:2025 includes the following significant technical changes with respect to
EN 14363:2016+A2:2022.
This document is one of the series EN 14363 Railway applications — Testing and Simulation for the
assessment of running characteristics of railway vehicles as listed below:
— Part 1: General;
— Part 2: Safety against derailment on twisted track;
— Part 3: Stationary tests that are not obligatory on European level;
— Part 4: On-track testing;
— Part 5: Simulations and calculations;
— Part 6: Background information to the EN 14363 series of standards.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
It is not necessary to require further assessment of vehicles which have been already assessed under
the conditions of previous standards in this field. Test results achieved under the conditions of the
previous standards remain valid and can be used for the extension of field of application of a vehicle or
vehicle design according to this series of standards.
Introduction
General information for the application of this document is given in prEN 14363-1:2025.
1 Scope
This document applies to all railway vehicles including OTM’s and Road-rail machines, which are
operated on the heavy rail network with standard track gauge 1 435°mm and nominal static vertical
wheelset forces up to 350 kN.
This document may also be applicable (partly or in full) to:
— rail systems with different track layout, e.g. urban rail systems and/or;
— rail systems with other than 1 435 mm nominal track gauge and/or;
— non-public rail networks and vehicles, e.g. mine rail systems.
NOTE For rail systems other than 1 435 mm track gauge or urban rail systems, the related post analysis, limit
values and test conditions could be different. They are specified nationally taking into account track design and
operating conditions.
This document contains methods to replace tests by simulations and/or calculations specified in
prEN 14363-2:2025, prEN 14363-3:2025 and prEN 14363-4:2025, completely or partly or to support
the assessment of railway vehicles according to this document.
