FIELD: construction.
SUBSTANCE: rail track device comprises two half-sleepers rigidly connected by a coupling bolt and made of a composite material. Rails are fixed on half-sleepers. Half-sleepers are equipped with power generators with electric contacts tightly installed under rails. Power generators in their turn are connected to each other by current conductors. Current conductors are placed in central holes, made in couplings along their longitudinal axis. The produced electric circuit is connected with the system of power supply of tracks. Generators are made from piezoceramics textured on the nanolevel, the axis of polarisation of which is located vertically and coaxially to rails.
EFFECT: device makes it possible to save power by its partial return to a system of control and power supply of rolling stock in process of rolling stock travelling along this section of the track.
