FIELD: railway tracks.
SUBSTANCE: inventions group relates to the field of maintenance of the superstructure of the railway track, in particular to under-rail devices, as well as to methods for the rapid restoration of the rail thread by level. The device is made in the form of a shell with holes. The shell expands when filled with a filler and thins when the filler runs out. The shell is laid on a natural or artificial track support directly or through a gasket. The shell interacts with the rail directly or through a spacer. The ends of the shell are equipped with connection devices with gaskets and a support. When restoring the track, the shell is placed under the rail directly or through spacers and filled with filler. The expanding shell raises the rail to a predetermined level and is fixed.
EFFECT: efficiency of restoring the temporary performance of the railway track is increasing.
