ResumoWe have developed a new-concept bogie for gauge-changeable trains that is applicable to both standard gauge 1,435-mm line and meter gauge 1,067-mm line. The bogie must therefore feature good running stability at high speeds on standard gauge lines as well as high running performance on the curves of meter gauge line. It adopts a direct-drive motor system to enable the motor to be mounted directly to the wheels, an independent wheel system and a wheel-set steering system. The independent wheel system provides the bogie with good running stability at high speeds with a short wheelbase. We tested the model on our rolling stock test machine, and confirmed that no stability problems occurred at speeds of up to 500 km/h. We also conducted high-speed performance testing at the Transportation Technology Center Inc. in Pueblo, Colorado, USA, and on the Sanyo Shinkansen line in Japan at speeds of over 200 km/h.
