FIELD: railway transport; maintenance and repair of rails without removing from bed. SUBSTANCE: defective section of rail is cut out and ends of rails are released at both sides. Then rails are lifted by 1.0-1.5 mm and fixed in this position. Rails are welded by aluminothermic fusion welding method. If length of defective section exceeds 70 mm, at least 3 m of rail is cut out and sound section of rail is installed in its place. Then aluminothermic fusion welding of butt ends is carried out. EFFECT: reduced time taken for repair, enhanced quality of repaired rail section. 5 cl, 1 dwg
