High-speed railway tracks require high quality track and accurate maintenance, but rail irregularities in main lines are inevitable. These irregularities are important sources for dynamic excitation. For the safety of trains at higher speed, the size of irregularities must be limited. In this paper, according to the Chinese Railway Standard, the wheel load reduction ratio is introduced. Based on this ratio, the limitation for rail irregularity size is presented. Dynamic responses of track due to "V" shaped irregularity and rail corrugation are treated.
