FIELD: transport engineering. SUBSTANCE: invention relates to elevated and overhead road transportation systems using rail track structures. According to proposed invention, hollow housing I of cylindrical shape accommodated prestressed longitudinal load-bearing member 2, and space between housing and assembled member is filled with filler 3. Prestressed longitudinal load-bearing member 2 is made in form of several wire ropes distributed over cross section of rail, and walls of housing are made closed. Different versions of distribution of wire ropes over cross section of rails at optimum ratio of areas of cross section of rail housing and wire ropes can be used. EFFECT: increased load-bearing capacity of rail used in transportation system. 8 cl, 8 dwg
