<p>Method for improving the vibration absorbtion of a railway track supported on a bed of ballast, more especially a ballast bed lying in a tunnel, on a fly-over or another artificial construction, the track consisting of rails supported by sleepers extending in a lateral direction, characterised in that the track is lifted, the ballast lying above the level of the supporting surface is removed, a plate of a vibration energy absorbing material is placed between the supporting surface of the ballast bed and the sleepers, and thereafter the track is lowered again, and a track formed by such a method.</p> |
