Abstract In this paper, we introduce that noise reduction can be realized by corrective grinding at rail joints of the bridge section. The noise level was reduced by about 4 to 5 dB before and after rail corrective grinding. Also in the frequency characteristic analysis, the noise reduction effect was recognized in a wide frequency band of 50 to 8 k Hz. Furthermore, In light of the results delivered by this corrective grinding, we implemented corrective grinding at rail joints in a continuous, roughly 250-m section, and measured noise levels. Approximately 10 dB noise level was reduced before and after rail corrective grinding, and the noise level was reduced in all frequency bands.
