FIELD: transport engineering. SUBSTANCE: invention relates to transportation systems with track structure close to overhead or monorail type. Proposed system contains main and auxiliary lines secured on base at different levels in spans between adjacent supports. Said lines are rigidly interconnected. Main line is coupled with auxiliary system of different height supporting members made in form of suspensions or posts spaced over entire span at intervals complying with definite relationships. Auxiliary line is secured with downwards sag. When building the system, first power member of auxiliary line is stretched on anchor supports and secured on intermediate supports, and fixing of relative position of main and auxiliary lines is carried out over span by variable-height supporting members meeting designed distance between lines in each point of span increasing to middle of span. Proposed group of inventions is aimed at increasing spans between adjacent supports at preservation of speed characteristics of system and rigidity of track structure. EFFECT: improved reliability of system. 20 cl, 16 dwg
