The invention relates to the field of transport, particularly, to rail transport systems with string-type track structure and represents, at least, one rail cord (3), tensioned above the foundation (1) between anchor (2) supports, which contains at least three discrete load-bearing elements (4), prestressed in longitudinal direction and positioned on the same line L in the cross section of the rail cord (3). The discrete load-bearing elements (4) are fixed resting on the caps (5) of intermediate (6) supports, with use of cross bulkheads (7).
Hereby, each discrete load-bearing element (4) contains contact surface K, continuous along the entire length of the rail cord (3), configured with the possibility of forming in totality, by all discrete load-bearing elements (4), of the rolling surface N of the rail cord (3) for self-powered wheeled vehicle (9), whereby the profile of the tread surface Z of wheels (10) mates with the profile of the rolling surface N of the rail cord (3) in places of fastening thereof on the caps (5) of supports (2) and/or (6).
