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.
