FIELD: construction.
SUBSTANCE: invention relates to a design of the track superstructure, namely, to composite sleepers. A tight body of a sleeper is made of plastic and has the outside shape of a cross section and dimensions of a regular wooden sleeper, inside it is filled tightly with a wooden bar of a rectangular cross section adjacent to the body walls. The volume of the wooden bar makes 93-97% of the total volume of the regular wooden sleeper.
