Abstract (en)
[origin: EP1258563A2] The railway permanent way has sleepers (3) embedded in cast concrete or asphalt (6), especially two-part concrete sleepers, together with elastic sound absorption units (10,11). The elastic damper underlays (15,16) for the sound absorbers hold them so that they cannot slide across the track. The sound absorbers between the rails (4,5) are on damper strips, with upright lips (17) to grip with a centering action between the sound absorbers and the heads of the sleepers. The lips have a conical shape, tapering upwards.
