The Dutch railways plan to increase the amount of trains and their running velocities to avoid overcrowded trains during rush hours. Pedestrian discomfort or danger at platforms can be caused by trains which are allowed to pass small railway stations at high speeds up to 140 km/h. A number of these railway stations lay underground, where wind gusts caused by trains are amplified by space confine-ment. The purpose of this study is to evaluate the effect of passing passenger and freight trains on the wind flow induced inside an un-derground tunnel by means of transient CFD simulation.
