FIELD: restoration of rails of railway road without dismounting them. SUBSTANCE: method comprises steps of cutting off defective portion of railway road rail; placing detachable form around rail ends in zone of welding gap; arranging over form reaction crucible filled with dose of aluminothermic mixture and performing welding; additionally heating rail ends and melt metal poured to welding gap at time period of feeding last doses of melt metal to space over rail heads; after solidifying melt metal cooling welded joint and zone near it by means of compressed air jet until temperature 250-300C and further - cooling it in air. EFFECT: possibility for making welded joint whose strength is equal to that of base metal with enhanced cyclic endurance due to additional cooling. 1 dwg
