Anemometers for operation control are mostly installed close to railway structures. Railway structures might therefore influence anemometer wind velocity data readings. The authors investigated the influence on the wind velocity of the anemometer position around typical railway structures through wind-tunnel tests and field wind observations. In the case of single-track embankments with a height of 6.5m from the ground surface, the increase in wind velocity on the leeward side was greater than on the windward side of railway structures, for heights up to 4m above rail level, as the wind direction approaches a 90 degree angle to the longitudinal direction of the railway structure.
