It was determined that the vibration amplitude of the tail car is greater, especially in a tunnel, than that of the other cars in a high-speed train, on which aerodynamic force exerts various effects. However, few aerodynamical studies have been conducted and little knowledge has been obtained. To clarify the aerodynamical effects on the train, we carried out a three-dimensional unsteady Navier-Stokes simulation. In order to verify the simulation results, a wind-tunnel experiment was performed. The pressure distributions were compared between numerical and experimental results and running test data available. Surface flow patterns were also compared between numerical and expermental results. These showed good agreement, verifying the simulation results.
