According to the decrease of the three-axle bogie for locomotives, the need for diminution of the gauge widening in curved track has been pointed out by rail maintenance division. Meanwhile, bolsterless bogies which have no side bearer are employed in many railway vehicles recently, and it is expected that various steering bogies will be employed in the near future. For vehicles which have these bogies, the gauge widening keeps its effect on curve negotiation even now. In this study, the dynamical analysis is carried out about the relationship between the gauge widening and the track load, considering the bogie mechanism. Numerical simulation is used for the analysis, and the effectiveness of gauge widening is summarized from dynamical viewpoint of two-axle bogie vehicles. Further, wear indices are introduced, and the wear tendency of flange and tread is estimated quantitatively.
