EN 14067-6:2010 (E) 8 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 (conventional, tilting, running direction).
