VIBRATION REDUCTION BY VIBRATION-PROOF MATS IN TOKYO SUBWAY

Noises and vibrations produced by trains running in a subway tunnel propagate through earth and sometime affect nearby buildings. While noises and vibrations resulting from the contact of wheels and rails are the principal source, the most effective way to reduce the problem is to alter the track structure. Vibration-proof mats of used rubber tires are used under the ballast of the Chiyoda Line. They functioned as desired but the track settled about 3 mm on account of reduced elasticity.
