We have been developing a new concept bogie, namely that for the gauge-changeable train applicable, for both standard gauge 1435mm line and narrow gauge 1067mm line. So this bogie has to have both high running stability at high speed on the standard gauge line and high running performance on curves of the narrow gauge line. This bogie adopts the direct drive motor system to mount a motor directly on the side of a wheel, independent wheel system, and wheel-set steering system. The independent wheel system provides this bogie with a high running stability at high speed with a short wheel base. We tested this bogie on our rolling stock test machine, and confirmed that no stability problems were found at high speed of 500km/h. Also we conducted a high speed performance test at the Transportation Technology Center Inc in Pueblo, Colorado USA, and on the Sanyo Shinkansen line in Japan over 200km/h. This paper discusses high speed performance of this bogie and its construction.
