The modeling methods as dynamics analysis was considered about the wheel /rail tangential force which affects various running ability of high speed railway vehicles, such as running stability, comfort, curving negotiation, and safety to derailment. In the case of a high speed railway, the driving force which balances to the train resistance is needed, even when running at the constant speed. So the traction force and the spin, in the quasi- state running condition, influence the saturation characteristics of wheel/rail tangential force, and generate the error which cannot be disregarded to lateral oscillation analysis of driven vehicles. Two alternative models in consideration of traction force and the spin of wheel /rail tangential force are devised. As a result of verifying by comparison with a real vehicle run, the necessity of raising the accuracy of analysis further was accepted. Nevertheless, the second method would be fully equal to use as a good approximation.
