Abstract At first,the paper introduces the“ general situation of the standard-narrow gauge train of the next generation”trial-produced by Japan. During this new-type train running between the standard gauge railway and the narrow gauge railway through a wheel base exchange rail with a length of about 20 meters.the wheel-base of the train may be changed automatically within 2 minutes,and after locked automatically.the train can run continuously without hindrance. In view of there are three different track gauges(1 135,) 067 and 1 000 mm)of railways in China and Southeast. Asia,the author proposes the following suggestion,i. e.developing a new-type train whose wheel-base may be changed automati?cally under the three different track gauges,so as to promote the implementation of international rapid through traffic as soon as possible.
