Zusammenfassung:	FIELD: ferrous metallurgy, in particular, rail production. SUBSTANCE: method involves providing single-pass straightening of nonquenched or thermally strengthened rails on roller straightening machine, with first force applying point being offset in vertical plane for 30-80 mm; moving rail between first and third force applying points till deflection value reaches 0-2 mm. EFFECT: increased efficiency and improved rail rectilinearity. 2 dwg, 1 tbl, 1 ex
