We analyzed the distribution of wind velocity and air temperature on Shinkansen platforms at Station 'A' using Computational Fluid Dynamics (CFD). We focused on standing trains and high-rise buildings around the station in the factors of the influence of distribution of wind velocity and air temperature on platforms. When the trains were present on Shinkansen platforms, wind velocity ratio on platforms was one-third of that when absence of trains, and air temperature was 0.5 to 0.7K higher than that observed when absence of trains because of wind barring and heat generated by trains. When both the high-rise building absent on the windward side of the platforms and the trains were absent, air temperature of platforms was 0.5K lower and wind velocity ratio was 3 to 5 times higher than that observed when the highrise building was present. Thus, present trains blocked strong wind from the outside of the platforms, and also rose air temperature on platforms.
