To verify the effects of rail damping devices in the rail corrugation treatment for vibration reduction tracks,rail damping devices were added to a ladder-type sleeper track and a steel-spring floating slab track,respectively,in this study.The vibration and trackside noise characteristics of the two vibration-reduction tracks were reported,and the development of rail corrugation was tracked.The results show that the rail damping devices installed on the ladder-type sleeper track can achieve positive effects in vibration and noise reduction in a wide band range,which can reduce rail vibration and trackside noise by 9.7 dB and 11 dB(A),respectively.The rail damping devices installed on the steel-spring floating slab track can reduce rail vibration and trackside noise by 8.3 dB and 3 dB(A),respectively,within their operational frequency range.Long-term tracking tests revealed that the installation of rail damping devices can at least halve the rate of rail corrugation development on vibration reduction tracks.
