The invention relates to a noise reducing track covering comprising cover elements (6, 7) arranged on the track. The cover elements (6, 7) have a sheet- like base (8) with a layer (10) on the upper side (9) thereof for the rooting of plants (11). The cover elements (6, 7) are provided with support lugs (15) on the edges thereof facing the rails, which engage in lateral recesses in the rails with intermediate elastomer profiles (16). The cover element (6) placed between rails are mounted exclusively by means of said support lugs (15) on the rail (2, 2') and bridge the space (17) between the rails in a self- supporting manner. Cover elements (7) connected to the outside of the rail are supported on one side with the supporting lugs (15) thereof on the rails and on the other side on foundations (18) and bridge the space between the rails and the foundations in a self-supporting manner.

L'invention concerne un garnissage pour voie ferrée réduisant les nuisances sonores et composé d'éléments de garnissage (6, 7) placés sur la voie ferrée. Ces éléments de garnissage (6, 7) comportent une base (8) sous forme de plaque, dont la face supérieure (9) est revêtue d'une couche (10) permettant l'enracinement de plantes (11). Ces éléments de garnissage (6, 7) présentent également, sur leurs bordures faisant face aux rails, des taquets de soutien (15) s'engageant dans les évidements latéraux des rails, des profilés élastomères (16) étant intercalés entre les taquets et les évidements. Les éléments de garnissage (6) placés entre les rails d'une voie ferrée ne sont fixés aux rails (2, 2') que par ces taquets de soutien (15) et passent, en porte-à-faux, par-dessus l'espace (17) situé entre les rails. Les éléments de garnissage (7) raccordés aux rails par l'extérieur sont, d'un côté, fixés aux rails par leurs taquets de soutien (15) et, de l'autre, montés sur la fondation (18), lesdits éléments de garnissage passant, en porte-à-faux, par-dessus l'espace situé entre le rail concerné et la fondation concernée.
