It is necessary to control the noise and vibration with a high frequency caused by various trains, not only nearby the railway, but also in the station area. An innovative rail-damper was fabricated and evaluated for its effectiveness in vibration control and noise suppressing. From a long-term monitoring, rail-damper can reduce effectively the vibration and noise acceleration level, both along tracks and in platform. The results indicated that as the track was masked by the rail-damper, the train noise equivalent sound level can be reduced more than 3.6 dB, and the vibration acceleration level could be reduced by an average of 6.7dB. For the vibration of the platform, the acceleration level was reduced by an average of 9.3dB. The rail- dampers can preferentially reduce the high-frequency part of the site vibration. The study herein would be useful to understand the feasibility of rail-damper for the noise and vibration control for the railway engineering.
