This paper presents improvement of isolation performance of the single-axle truck for railway vehicle. It has several advantages over conventional two-axle bogie in decreasing weight of truck and curve performance. However, it was said that the isolation performance in vertical excitation, such as rail joints had been problem to be solved. The authors propose the modification of vibration system in the single axle truck to improve the reduction of vibration in vertical direction. The two-axle bogie has three degrees of freedom with pitching motion of bogie frame and it is effective to reduce the vibration of the vertical direction. Therefore, the pitching motion of the truck frame is added by modification of the setting of secondary suspension in the single axle truck. The theoretical examination, numerical simulation were made to confirm the effectiveness of the proposed system. Experimental setup is also made and the improved performance are proved by experiments.
