Abstract

Measurements of wind flow and pressure fluctuations induced by train passing on station platform have been conducted. Test conventional trains have a different nose shapes - bluff nose and wedged nose. The bluff nose train influence peak value of pressure fluctuations on station platform three times more than the wedged nose train for train speed of 108 km/h. Also, air flow induced by the bluff nose train passing is three times more than the wedged nose train passing. Current study shows that the gust induced by the bluff nose conventional train may threaten a passenger's safety on station platform in proximity to train passage.
