So far today, there is a speed limit by the radius of curve based on operation regulation in domestic railway, however a study for the maximum running speed at the curved section without any derailment would be necessary. But it is very hard to analyze the train derailment safety quantitatively at the curved section because of the diversified affect parameters including the complex interaction between wheel and rail, the train conditions such as the shape of wheel, suspension system, the track conditions such as the radius of curve, cant, transition curve, and the operation conditions, etc. The two major factors related to the running safety of railway vehicle are classified as the railway vehicle and the track condition. In this study, when the railway vehicle passing through curves of actual track conditions of subway line NO.3 in seoul (Ankuk⟷Jong no 3ga, Express Bus Terminal⟷Seoul Nat'l Univ. of Education, Yeonsinnae⟷Gupabal), the effect that has influence on running safety depending on rail inclination.
