Lateral forces between wheels and rails must be reduced in order that rolling stock runs safely and smoothly on curved tracks. Excessive lateral forces will cause not only derailment of rolling stocks but also destruction of tracks, rail corrugation, track irregularity, squeal noise and wear of wheel and rail. In this paper the authors study 2 methods to reduce lateral forces and improve running performance on curved tracks without development of new wheel profiles and bogie structures. According to the results of numerical simulation, the authors conclude that "expansion of gauge widening" and "increase of tie plate angle of inner rail", ie. "change of inner rail inclination", can get sufficient rolling radius difference and increase running performance on curved tracks. "Expansion of gauge widening" is effective both in "arc wheel profile for linear metro" and CS wheel profile, on the other hand, "increase of tie plate angle" is effective in "linear metro arc wheel profile".
