Overview

EN 14067-5:2006/FprA1 - "Railway applications - Aerodynamics - Part 5: Requirements and test procedures for aerodynamics in tunnels" is a CEN European Standard (amendment FprA1) that addresses aerodynamic loading caused by trains running in tunnels. The amendment updates the standard’s relationship to EU Directive 2008/57/EC (rail system interoperability) via Annex ZA and clarifies conformity assessment links with Technical Specifications for Interoperability (TSIs). This document defines requirements and test procedures for evaluating tunnel-induced aerodynamic effects such as pressure waves and transient loads.

Key Topics

• Scope and objective: Evaluation of aerodynamic loads generated by trains in tunnels and requirements for their measurement and assessment.
• Test procedures: Prescribed methodologies for quantifying pressure changes and aerodynamic effects in tunnel environments (measurement, instrumentation and test protocols are addressed in the standard).
• Performance criteria: Limits and health/safety criteria for pressure variations in tunnels (including relevance to passenger comfort and medical/health criteria).
• Conformity and assessment: Procedures for assessment of conformity and suitability for use, including how results relate to interoperability requirements.
• Regulatory alignment: Amendment FprA1 maps standard clauses to the Essential Requirements of EU Directive 2008/57/EC and to relevant TSIs (HS TSI RST/INF, CR LOC/PASS RST TSI, CR TSI INF).
• Aerodynamic loading aspects: Consideration of steady and transient loads, maximum pressure variations, and technical compatibility between rolling stock and infrastructure.

Applications and Who Uses It

This standard is practical for professionals involved in the design, testing and certification of railway vehicles and tunnel infrastructure:

• Rolling stock designers and manufacturers assessing vehicle nose shapes, pressure mitigation features and structural load resistance.
• Tunnel and infrastructure engineers evaluating tunnel cross-section, ventilation, and safety measures against pressure waves.
• Testing laboratories and measurement specialists implementing standardized tunnel aerodynamic test procedures and instrumentation.
• Railway operators and infrastructure managers assessing compatibility of vehicles with existing tunnels and planning upgrades.
• Certification bodies and conformity assessors verifying compliance with TSIs and EU interoperability requirements.

Related Standards

• EN 14067 series (other parts on railway aerodynamics) - for vehicle and train aerodynamic characteristics.
• TSIs and draft TSIs referenced in Annex ZA: HS TSI RST, HS TSI INF, CR LOC and PASS RST TSI, CR TSI INF.
• EU Directive 2008/57/EC - interoperability requirements that this amendment aligns with.

Keywords: EN 14067-5:2006/FprA1, aerodynamics in tunnels, railway aerodynamics, pressure variations, test procedures, tunnel aerodynamics, interoperability, TSI, rolling stock, infrastructure.

This draft amendment is submitted to CEN members for unique acceptance procedure. It has been drawn up by the Technical Committee
CEN/TC 256.
This draft amendment A1, if approved, will modify the European Standard EN 14067-5:2006. If this draft becomes an amendment, CEN
members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of this amendment
into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made
by translation under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same
status as the official versions.

Foreword
This document (EN 14067-5:2006/FprA1:2010) 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 Unique Acceptance Procedure.

The “Recast” Directive 2008/57/EC of the European Parliament and of the Council on the interoperability of
th
the rail system within the Community was published on 17 June 2008. The two previous EU Directives
96/48/EC and 2001/16/EC on the interoperability of the High Speed and Conventional rail systems within the
th
Community will therefore be repealed with effect from 19 July 2010. At this date the harmonised standards
for the railway field will have to refer to the new Directive.
Annex Z is amended to address this need.
1 Modification to the Foreword
Replace the third and fourth paragraphs with the following:
"This document has been prepared under a mandate given to CEN/CENELEC/ETSI by the European
Commission and the European Free Trade Association, and supports essential requirements of EU Directive
2008/57/EC.
For relationship with EU Directive 2008/57/EC, see informative Annex ZA, which is an integral part of this
document."
2 Modification to the Annex ZA
