Overview

EN 14067-4:2013/prA1:2017 - Railway applications - Aerodynamics - Part 4: Requirements and test procedures for aerodynamics on open track (CEN) defines requirements, test procedures and conformity assessment for railway aerodynamics on open track. The standard focuses on aerodynamic loadings and resistance to motion for rolling stock and related infrastructure. It does not apply to freight wagons and is intended for operation on gauges GA, GB and GC per EN 15273; the test methodology may be adapted to other gauges.

Key topics and requirements

• Scope and applicability
  • Covers open-track aerodynamic performance of locomotives and passenger rolling stock (excluding freight wagons).
  • Applies to gauges GA, GB, GC with adaptation guidance for other gauges.
• Aerodynamic parameters
  • Requirements for assessing aerodynamic loadings on vehicles and nearby infrastructure.
  • Assessment of aerodynamic resistance to motion (energy and performance impacts).
• Test procedures
  • Outlines methodological approaches for on-track testing and evaluation (procedures are normative within the standard).
  • Emphasizes repeatable measurements and conformity assessment processes.
• Conformity & regulatory linkage
  • Includes provisions for conformity assessment to demonstrate compliance.
  • Amendment prA1:2017 adds Annex ZA, relating the standard to EU Directive 2008/57/EC and corresponding TSIs - providing a pathway to a presumption of conformity when cited in the Official Journal of the EU.

Practical applications and users

Who uses EN 14067-4:

• Rolling stock designers and aerodynamic engineers validating vehicle performance on open track.
• Infrastructure engineers assessing aerodynamic impacts on platforms, trackside equipment and structures.
• Test laboratories and accredited organizations conducting on-track aerodynamic tests.
• Certification and conformity assessment bodies, vehicle manufacturers and system integrators preparing technical files for interoperability.
• Railway operators and planners evaluating energy consumption and operational effects due to aerodynamic resistance.

Practical uses:

• Verifying slipstream, head-pressure and pressure-pulse effects on platforms and trackside personnel (as aligned with rolling stock and infrastructure requirements).
• Quantifying aerodynamic resistance to inform energy-efficiency and traction design decisions.
• Supporting interoperability and regulatory compliance under EU TSI frameworks via Annex ZA.

Related standards

• EN 14067 series (other parts) - see EN 14067-6 for cross wind assessment.
• EN 15273 - gauges GA/GB/GC referenced for applicability.
• Relevant TSIs and Commission Regulations (e.g., Reg. 1302/2014 and 1299/2014) referenced in Annex ZA for regulatory conformity.

For practitioners seeking compliance and reliable on-track aerodynamic evaluation, EN 14067-4 is the primary European standard for open-track aerodynamic requirements, testing and conformity processes.
