This paper proposes on-board turnout system which makes use of power-steering railway bogie with independently rotating wheel. The on-board turnout system mainly consists of three elements as bogie structure, bogie control methodology and rail structure. In this paper, the bogie control methodology which realizes robust tracking for desired wheel lateral displacement is mentioned. In the control of wheel lateral displacement to the desired value, the estimation of lateral displacement between rail and wheel is required. In this paper, the estimation method using rotating velocity difference of two paired wheel is considered. Using the estimated value, tracking control of wheel lateral displacement is considered. Numerical simulation shows the robustness of tracking control. The running experiment with scaled model vehicle on mock-up rails proves the success of this control and developed rail structure.
