Verification of Control Effect of Rail Corrugation by Using Resilient Rail Pad

Abstract

In this study, we continuously measured rail surface roughness in the track where the rail was corrugated, and resilient rail pad is used on a trial basis. The authors' previous study shows that there are multiple types of growth factors for rail corrugation. In an investigation track, growth factor of rail corrugation was identified as "anti-resonance phenomena in total system of track and vehicle". As a result of the field investigation, it was confirmed that the growth rate of the rail surface roughness of the rail corrugation was controlled in the track by using resilient rail pad as compared with in the track by using conventional rail pad.
