Introduction
Trains running on open track are exposed to cross winds. The cross wind safety of railway operations
depends on vehicle and infrastructure characteristics and operational conditions. Important
parameters are:
— aerodynamic characteristics of the vehicle;
— vehicle dynamics (e.g. mass, suspension, bump stops);
— track gauge;
— line characteristics (radius and cant of the track, height of embankments and bridges, walls near the
track);
— wind exposure of the line;
— operating speed, mode of operation (non-tilting, tilting, running direction).

1 Scope
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.
