FIELD: railway track construction. SUBSTANCE: device has two cover plates 1, rail chair 4 with bolts for connecting rails 2 which are located on sleepers 3. Ends of rails are made step-like in plan. Length of step is made within l min = 65 mm, L max = 0.8 H, width of step b = B/2, where H - height of rail, mm, B - width of rail head, mm. Made on stepped ends of rail in running surface are bevels with angle of β and length of l1= equal to 10-20 mm from ends of rails. Application of aforesaid embodiment of device allows for prolonging service life of rails. EFFECT: higher efficiency. 2 cl, 2 dwg
