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.

Železniške naprave - Aerodinamika - 6. del: Zahteve in preskusni postopki za oceno vpliva bočnega vetra

Ta dokument podaja smernice za načrtovanje vpliva bočnega vetra na železnice.
Ta dokument se uporablja za vsa potniška vozila, lokomotive in pogonske vagone (z največjo hitrostjo vlaka od 140 km/h do 360 km/h) in tovorne vagone (z največjo hitrostjo vlaka od 80 km/h do 160 km/h) ter za tirne širine od 1435 mm do vključno s 1668 mm. Za potniška vozila, lokomotive in pogonske vagone z največjo hitrostjo med 250 km/h in 360 km/h je določena zahteva, da se dokaže stabilnost pri bočnem vetru. Ta standard se ne uporablja za lahka železniška vozila in mestna železniška vozila.

This European Standard was approved by CEN on 3 March 2018 and includes Amendment 1 approved by CEN on 6 June 2022.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists 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-CENELEC Management
Centre has the same status as the official versions.
