A railway vehicle with single-axle trucks enables to decrease maintenance cost of wheels and rails due to their high curving performance and its lightweight. However, there is a disadvantage in ride comfort due to vertical vibration. In view of such a situation, we proposed a new design concept of the single-axle trucks, which is movable in pitch rotation similar to the two-axle bogies. In this paper, we carried out an analytical study on vibration isolation characteristics, ride comfort and curving ability of the new trucks. As a result, it was apparent that the characteristics of vibration isolation improved in the frequency range less than 10Hz. It is also evident that axle dampers enabled to suppress the vibration of car-body at a high frequency region. Finally, we verified the high curving performance of the new trucks.
