Abstract

An infrastructure for railway tracks with continuous elastic support has two rails forming the track supported via elastic intermediate layers with their lateral limiting surfaces located underneath the rail head against the inner lateral limiting surfaces of a frame consisting of two frame halves and underneath each rail a longitudinal plate consisting of concrete. One of the frame halves rests against a first lateral wall of a trough while the other frame half rests via a wedge against the second lateral wall of the trough.
