FIELD: transport engineering. SUBSTANCE: system has a vehicle with wheels 6 which rest against rails 1. Rolling surfaces of head 3 of rail 1 and wheel 6 engaging with one another are made with equidistant roughnesses of convex shape with height equal to 1/600-1/300 of the height of head 3 of rail 1. These surfaces on the area of 28-32% are made with roughnesses at an angle of 50-60° relative to longitudinal surfaces of symmetry of the rail and the wheel. EFFECT: improved structure. 4 cl, 15 dwg
