EN 14067-4:2005+A1:2009

This European Standard applies to train-induced aerodynamic loading on open track caused by:-trains passing a permanent or temporary structure;-trains passing a person who is alongside the track;-two trains passing each other.This European Standard applies to open air structures of any length and closed structures of a length less than 20 m enveloping the tracks. For closed structures enveloping the tracks that are longer than 20 m prEN 14067-5 applies.For effects caused by cross winds, the aerodynamic phenomena are described in prEN 14067-6.In addition, this European Standard applies to the resistance of motion for trains in open air.
