FIELD: transport.;SUBSTANCE: proposed method consists in using rail strip with L-like ledges arranged opposed to make four-head unit and providing said rail strip with outer lateral heads. Clearance under said L-like ledges is kept smaller than width of standard rail pair feet. Said rail pair is fitted into pocket between L-like ledge to rotate each pair about lengthwise axis: one - clockwise and another one - counter clockwise to contact between lateral edges of their feet. Alloyed suds are fitted into rail web bores, plate washers are fitted thereon and fastening nuts are snugged on. Hydraulic jacks are used to hammer rails down. Wedges arranged between feet are used to fit feet under L-like ledges to close clearance under feet to ensure dense contact between feed and rail strip. Nuts are tightened by speeder wrench to fix rail pair with rail strip and to form solid four-head rail unit.;EFFECT: longer life.;2 dwg
