According to the marked decrease of the three-axle truck for locomotives, the need for diminution of the slack in gauge has been pointed out by rail maintenance division. About this problem, the curving performance under the presence of gauge widening has been investigated with the consideration of truck mechanism and wheel shape. In this study, the modification of wheel tread shape treated in the 3rd report is reconsidered by using an inclination diagram of wheel tread and rail head. Simulation results show that the tread shape obtained by above diagram can get further availability of gauge widening. Further, it is shown that the effectiveness of gauge widening can be obtained also in a vehicle assumed to negotiate very tight curves at low-speeds.
