RAIL TRACK OF STRAIGHTLINE HIGH-SPEED RAILWAY Russian patent published in 2017 - IPC E01B1/00 

FIELD: construction.

SUBSTANCE: rail track of a straight-line high-speed rail includes rails with pads to join them end-to-end, which are installed with a clearance to compensate for the strain of rails during temperature change in both summer and winter. The rails are mounted on sleepers and on the embankment ballast of the railway bed. Unilateral cantilever beams are made on the rail ends on the left and right side of the rail from its middle or in each rail in its head. Each cantilever beam is connected relative to a next rail with the planes of said beams overlapping with the possibility of their longitudinal displacement, turning a rail track into a jointless one. Between the pads and the neck of the rail are cavities in which the lower parts of the cantilever beams are arranged to prevent slipping of said cantilever beams along their upper planes.

EFFECT: creating a jointless track.
