A series of filed tests have been performed to investigate the aerodynamic effects on platform of the railway station during the passage of train that can be unpleasant and even dangerous to the pedestrians. To assess the aerodynamic effects on the platform, two aerodynamic properties has been measured; one is the wind gust induced by the train and the other is the pressure pulses generated when the nose and the tail of train passes. To measure these aerodynamic properties during the train passage, an array of hot-wire type anemometers and several sets of pressure transducers have been used, respectively. This paper deals with the filed test on conventional railway at about 100km/h operational speed, in which total 34 measurements has been made at the Bugok station in Seoul-Busan line for Saemaul-ho and Mugungwha-ho train. The results showed dramatic differences in the aerodynamic features between the two trains that are supposed to originate from the contrasting nose shapes of the trains.
