The field survey on station Y was conducted from August to October 2009. Railway tracks of station Y run along the moat from north to south and the platform is lower than the surrounding topography. According to the field survey, dominant outdoor wind from north and south was observed along the railway tracks. Air temperature of the wind was lower than the neighbouring urban area by 1°C in the evening, implying that cool winds in the north-south direction was blowing along the railway tracks. Wind along the railway tracks could not be introduced to the concourse efficiently because of the wall and closed windows in the north-south axis. On the other hand, these walls and windows shield the station from strong winds like typhoon. Adjustment of openings in the north-south axis would improve of thermal comfort and protect from strong winds in station Y.
