This paper proposes a new rail vehicle concept. A three axles-one-unit vehicle with a self steering single axle. Usually a single axle vehicle requires a short and wide car body which is a system design of the next generation of railway vehicles. The authors propose a new three axle one unit vehicle steering a single axle truck for the railways. This proposed vehicle uses three trucks and has the standard body length of a conventional train. It has the merit of decreasing elastic body vibration by using a lightweight car body and by setting a truck in the middle of the car body. This system design can provide high performance with respect to stability curving performance and axle load limitation. Analyses were made with multi body dynamic simulations and the basic characteristics were cleared. Finally a scaled model was made and tested. The proposed vehicles potential for high performance was proved from running experiments including curving.
