RESULTS OF THE RESEARCH PROGRAMME ON "NOISE AND VIBRATION REDUCTION FOR URBAN RAILWAY SYSTEMS" AND THEIR APPLICATION IN PRACTICAL OPERATION

The studies undertaken in the research programme on "Noise and Vibration reduction for Urban Railway Systems" have now reached a stage whereby promising approaches for reducing noise emission can be identified. For example, the screeching noise in curves can be eliminated by fitting the wheels with noise absorbers or by coating the track. Comprehensive measuring tests have shown that, in order to reduce the rolling noise, it is important that the wheels and rails should have a smooth contact surface. The studies currently being carried out on reducing sound transmitted by air are mainly concerned with making design changes to boogies and wheels. As far as sound conducted through solids and vibration are concerned, detailed information has been obtained on the insulating effect of different types of permanent ways. However, sufficient knowledge of the interactions of various influencing factors (tunnel, ground, etc.) has not yet been gained and further studies are therefore necessary.
