Ces composants sont pour la plupart en plastique \u00e9lastique et sont coinc\u00e9s entre les rails et les traverses en b\u00e9ton, comme l&rsquo;explique l&rsquo;Empa dans un communiqu\u00e9 de <a href=\"https:\/\/www.empa.ch\/web\/s604\/noise-reduction-of-rail-transport\" target=\"_blank\" rel=\"noopener\">presse<\/a> . Ils sont utilis\u00e9s pour prot\u00e9ger les rails.<\/p>\n<p class=\"bodytext\"> Cependant, les patins de rail existants ont des limites. Surtout si la protection des rails est consid\u00e9rablement augment\u00e9e, cela entra\u00eene en m\u00eame temps plus de nuisances sonores. Les chercheurs veulent maintenant r\u00e9soudre ce d\u00e9fi.

En m\u00eame temps, il peut r\u00e9duire le bruit ferroviaire et prot\u00e9ger les rails.<\/p>\n<p class=\"bodytext\"> Dans une prochaine \u00e9tape, les nouvelles semelles de rail seront test\u00e9es sur une ligne ferroviaire \u00e0 Nottwil en mars. \u00ab Ces patins de rail sont faciles \u00e0 fabriquer. Nous aurons besoin de pr\u00e8s de 400 unit\u00e9s pour le tron\u00e7on de 100 m\u00e8tres\u00bb, explique Bart van Damme du d\u00e9partement Acoustique et r\u00e9duction du bruit de l&rsquo;Empa.
