Railway applications - Aerodynamics - Part 6: Requirements and test procedures for cross wind assessment

This document gives guidelines for the cross wind assessment of railways.
This document is applicable to all passenger vehicles, locomotives and power cars (with a maximum train speed above 140 km/h up to 360 km/h) and freight wagons (with a maximum train speed above 80 km/h up to 160 km/h) and track gauges from 1 435 mm to 1 668 mm inclusive. For passenger vehicles, locomotives and power cars with a maximum train speed between 250 km/h and 360 km/h, a requirement to demonstrate the cross wind stability is imposed. This document is not applicable to light rail and urban rail vehicles.

Overview

EN 14067-6:2018/FprA1 is a European standard developed by CEN (European Committee for Standardization) that provides essential requirements and test procedures for cross wind assessment in railway applications. This standard is a part of the EN 14067 series focusing on the aerodynamics of railway vehicles. It specifically addresses the impact of cross winds on the stability and safety of trains, including passenger vehicles, locomotives, power cars, and freight wagons operating at various speed ranges.

This document applies to rail vehicles operating at high speeds - from 140 km/h up to 360 km/h for passenger vehicles, locomotives, and power cars, and from 80 km/h up to 160 km/h for freight wagons. It covers vehicles operating on standard and broad track gauges ranging from 1,435 mm to 1,668 mm, but explicitly excludes light rail and urban rail systems.

Key Topics

• Cross Wind Stability Requirements
  For passenger vehicles, locomotives, and power cars running between 250 km/h and 360 km/h, the standard mandates demonstration of cross wind stability. This ensures that trains remain safe and operational under challenging wind conditions.

• Assessment Guidelines
  The standard outlines precise methods to evaluate how cross winds influence train dynamics, including testing scenarios, wind speed conditions, and aerodynamic factors.

• Test Procedures
  Detailed testing methods are described, including wind tunnel tests, numerical simulations, and real-world trials that help assess the aerodynamic behavior of railway rolling stock when subjected to side winds.

• Applicable Vehicle Categories
  EN 14067-6:2018 covers all relevant rolling stock - passenger vehicles, locomotives, power cars, and freight wagons - ensuring uniform safety and performance criteria across the rail sector.

• Aerodynamic Parameters and Modelling
  The document includes updated tables and annexes that provide quantitative data for wind speeds, angles, and force coefficients critical to the cross wind evaluation procedures.

Applications

• High-Speed Rail Operations
  Ensures that trains operating at high speeds maintain stability and safety against cross wind forces, reducing the risk of derailment or passenger discomfort.

• Rolling Stock Design and Certification
  Manufacturers and railway operators can use this standard for the aerodynamic design and certification of new rolling stock, ensuring compliance with EU safety requirements.

• Infrastructure and Track Planning
  Used by engineers to understand wind impact on railway lines, informing placement of wind barriers and other protective measures.

• Regulatory Compliance
  Supports adherence to EU Directive safety mandates related to railway vehicle aerodynamics, facilitating smoother market access for rolling stock across European countries.

Related Standards

• EN 14067 Series
  Other parts of EN 14067 focus on general aerodynamic requirements, noise emissions, and testing methods for railway vehicles.

• EU Directives on Railway Safety
  EN 14067-6:2018 aligns with essential safety requirements stipulated by European Union regulations affecting rail transport.

• International Railway Aerodynamics Standards
  Complements global standards for aerodynamic safety assessment, aiding harmonization in international rail transport.

---

This standard is crucial for professionals in railway engineering, train manufacturing, and aerodynamic safety assessment, helping ensure rail vehicle stability in the presence of cross winds. Implementing EN 14067-6 supports safer, more reliable railway operations in diverse European climates and conditions.
