PROBLEMS OF ENVIRONMENT WITH VERY HIGH SPEED TRAINS
PROBLEMES D'ENVIRONNEMENT DES RAMES A TRES GRANDE VITESSE
The most careful research and development have been carried out to ensure that lineside dwellers are caused minimum inconvenience when trains pass by successively. The main factor that can be controlled is the level of noise caused by running and steel wheel on steel rail contact. Measures can in fact be taken on the track and in the train. In the train, efforts have therefore been directed to reducing the amount of running gear and employing a design that reduces the level of noise created at the rail. It has thus been possible, at a normal traffic density of five trains 400 metres long an hour, to achieve a level expressing inconvenience that does not exceed 70 dB (A). Track laid in cuttings enables noise to be reduced most appreciably and in certain cases it is planned to install opaque lateral screens.
