Description of the Related Art A conventional sleeper track is constructed by independently installing a plurality of horizontal sleepers such that rails are intermittently supported on a track bed. In this kind of pillow track, there is no particular problem if each pillow is immovable and uniformly supports the rails, but it actually sinks down over time due to the action of the wheel load, or due to the action of lateral pressure. There were problems such as sliding, etc., causing track deviations, which caused the sleepers to rattle and hanging on the rails, which should originally support the rails. .
