In order to run safeI } ・ and sm 〔〕 Dthly though curvcd tracks , the gauge of track has 1〕een widerled in curved sedions . In reGont years , hQwever . the gauge widening ( G 、 V ) was reduced due tD some causes , such as , the decrease of three − axle bogies , the increased accuracy of track maintenance , etc . But the GW has the original purpose tha 亡 gives the rolling radius difFerellce of inner /outer wheels whfch produces the steering 巳 ffect. The reduction ofGW may lead to the decrease of
