Compatibility between high speed running stability and good curving performance of railway vehicles has long been considered. In the design of vehicle parameters, the axle supporting stiffness is quite important for solving the trade〜off. On the contrary, the proposed bogie with steering yaw damper enables the vehicle to realize ideal curving performance on tight curved track while achieving high speed running stability. In order to verify the performance of the newly developed steering truck, the scaled model experimental platform with 1/10 model vehicle is orignnally made. In this paper, the theory of steering bogie to secure high speed running stability is explained. The design procedure is based on the hunting frequency analysis of wheelset considered as a system to be stabilized. Experimental results for the scale model vehicle with two single〜axle bogies show good performance for high speed running stability.
