As environmental protection becomes important, energy-saving for railways is promoted by various methods in recent years. As train speed becomes higher, it is very effective to decrease the aerodynamic drag of vehicles for energy-saving. The speed of conventional vehicles is lower than that of Shinkansen trains, but their maximum speed is higher than that of automobiles. On-roof and under-floor equipment are blunt in configuration. Therefore, for energy-saving, it is effective to decrease the aerodynamic drag of conventional vehicles. The aim of this research is to propose methods of decreasing the aerodynamic drag of conventional vehicles and estimate their effects. We measured the aerodynamic drag of vehicles with some different shapes of the on-roof and under-floor equipment by wind tunnel tests. These test results show that installation of larger under-floor equipment and fairing on both sides of on-roof equipment decrease the aerodynamic drag of vehicles.
