Abstract:

The rail corrugation on the track using Egg fastener becomes a serious problem on several operated lines of Beijing metro in recent years. The investigations and field measurements show the corrugation is mainly induced by the resonance vibration in the train/track system at 200-400 Hz. To suppress the growth of corrugation, a rubber pad is installed in Egg fastener. And two field tests are carried out on line 10 of Beijing metro to evaluate the effect of treating the rail corrugation. The running band roughness of corrugated rail in the test sections has been measured for about 6 mouths. The measurement results show that the measure of installing a rubber pad in Egg fastener is an effective treatment for controlling the growth of rail corrugation or reducing the corrugation to some degree.
