FIELD: lubricants. SUBSTANCE: invention is designed to be applied in rail-way transport area for reducing wear in wheel-rail friction couples in bent sections of way owing to using high-efficiency lubricants. Suitable lubrication composition contains low-molecular polyethylene representing high- pressure polyethylene production waste, spent diesel oil, and also sulfidizing agent and antifriction substance, said sulfidizing agent being organosulfur polysulfide polymers prepared from epichlorohydrin production waste and said antifriction substance finely crushed oil coke. EFFECT: achieved required efficiency, reduced cost, and improved environmental condition. 1 tbl, 10 ex
