FIELD: construction.
SUBSTANCE: group of inventions relates to railway track superstructure, in particular to rail transfer devices, as well as to replacement of switch rails. Transfer device contains a tongue-like rail, a guide rail, a connecting rail, as well as a support of a switch rail. Switch rail is connected to the connecting rail by welding. Under the welded seam there is a hole or cutout, the width of which is larger than that of the switch rail. When switch rail is replaced, separating cutter is made along weld seam or nearby weld seam.
EFFECT: reduced labor capacity of switch rail.
