Frame sleeper track

from Wikipedia, the free encyclopedia

The frame sleeper track is a type of railway superstructure that represents a compromise between sleeper superstructure and slab track .

Frame sleepers consisting of two long support beams with a cross sleeper at each end are laid on a conventional ballast bed. The rails are attached to the sleepers with common fasteners. Elastic intermediate layers are laid on the supports. The distance between the individual frame sleepers is very small, so that the rails rest almost continuously.

The frame sleeper track is slightly more expensive than a conventional superstructure, but cheaper than the slab track.
