This study considers high-speed train nose shapes which satisfy multiple aerodynamic characteristics. Aerodynamic drag, pressure variation around the nose which effects on an oncoming train and aerodynamic yawing moment of the tail car which causes a flow-induced train vibration in tunnels are estimated by wind tunnel experiments. We examined four types of nose shape as follows: 1) two-dimensional type, 2) straight top surface type, 3) parabolic top surface type, and 4) straight side surface type. The result shows the two-dimensional type is the best among them in almost all aspects.
