Scale model experiments were made to investigate the steady and unsteady airflow characteristics in an underground railway station. The experimental apparatus consists of a scale model of a two-layer underground railway station and train wind generators that simulate the steady and unsteady airflow caused by trains. The steady and unsteady airflows were measured with hotwire anemometers at several points of the station for several cases. The unsteady airflow patterns were almost identical to the estimated airflow patterns obtained from steady values. The method of reducing the train wind effect in a station by means of tunnel ventilation dynamic control was considered and its effectiveness was confirmed through experimentation.
