HEAT UP TEST OF LONG WELDED RAIL ON SLAB TRACK

To study forces acting on slab track caused by thermal expansion of long welded rail or of the concrete slabs, heating tests were conducted on a newly built section. Special effort was made to eliminate residual forces at the beginning of the experiment. It was proved that longitudinal force caused by welded rail acting through the track fasteners is about 60 percent of the design value. Lateral force and distortion of the track is comparatively small.
