“…Wind tunnel tests involve the simulation of not only flat ground, but also ground structures such as bridges and embankments. Furthermore, a turbulent boundary layer that simulates the average wind speed and turbulence intensities of natural wind is used for the air flows that act on a model vehicle [1][2][3][4]. Recently, wind tunnel tests have been conducted on model vehicles that simulate several vehicle cross-sectional shapes in order to investigate the relationship between the aerodynamic force and cross-sectional shape of the vehicle.…”

This paper presents an outline of recent studies on railway aerodynamics conducted in the Railway Technical Research Institute. Train aerodynamic effects increase significantly with the speed of trains, and cause various issues for railways. Since these issues closely affect train safety, convenience, and ride comfort, it is important to investigate these aerodynamic characteristics. Typical studies in this field, such as those on the effects of cross winds, aerodynamic devices of train vehicle and the effect of flow fields around trains in open sections and tunnels, are introduced in this paper.
