Railway applications - Aerodynamics - Requirements and test/assessment procedures (series; Parts 4 open track, 5 tunnels, 6 crosswind; anchored on Part 4)

Scope

Multi-part CEN series specifying the mandatory aerodynamic requirements and test/assessment procedures for rail vehicles: pressure-pulse and slipstream effects on open track (Part 4), pressure variations in tunnels (Part 5) and crosswind performance (Part 6). This entry anchors on Part 4; together the three parts form the type-test framework required for vehicles above roughly 140 km/h to demonstrate aerodynamic safety and passenger/trackside comfort for authorisation.
