MEASURES ASSOCIATED WITH IRON GIRDERS

Metal bridges present special problems in controlling the propagation of train-generated noise. The open-deck bridges used on the original New Tokaido Line are now receiving priority attention with regard to noise and vibration control. Main sources of noise of a train on bridge are the wheel/rail contact and the noises emitted by vibration of the bridge structure. Sound insulating walls and plates beneath the main structure are used. Vibration damping material is also applied to metal surfaces. Tests of total enclosure of bridges have also been conducted. Effectiveness of the various noise barriers are described.
