This paper proposes a new rail vehicle concept of three axles one unit vehicle with self steering single axle. Usual single axle vehicle required the short & width car body as a system design of next generation railway vehicle. However, Authors propose a new Three Axis One Unit Vehicle with steering single axle truck for railway vehicle. This proposal use three trucks in a vehicle with normal body length of conventional train, and this method has a merit to decrease elastic body vibration with light weight car body by setting a truck in the middle of car body. This system design can expect high performance for stability, curving performance, and axle load limitation. The analyses with multi-body dynamics simulations were made and the basic characteristics were cleared. Finally, 1/10 scale model vehicle was made and the proposed vehicle has a potential for high performance is proved from running experiments including curving.
