A rail track comprises a fixed surface (2) which supports the track, at least two rails (10) which incorporate a rail head (11), a groove (16), a rail slat (12) and a rail foot(13). Sound damping units are located near the rails and the lower sections and consist of reduced old rubber with a polyurethane binding. The units have upper and lower sides (33, 34) and edge and chamber sides (32, 31). The filling material is in the form of a beam and the upper side (33) of the filling member (30) has sound absorbing units.
