Energy-saving double-rail double vehicle

The invention belongs to the technical field of energy-saving double-rail double vehicles, in particular to an energy-saving double-rail double vehicle, comprising an upper deck, a lower deck, two groups of double-rail tracks, and two groups of track mounting posts. Each group of rail mounting posts are provided with an outer track and an inner track; bottom wheels of the upper deck are disposed on the outer track; top wheels of the lower deck are disposed on the inner track. The two decks oppositely run at the top and bottom of the double-rail tracks. A travel detection system is arranged on the rail mounting posts. Both the upper deck and the lower deck are provided with navigation systems which are connected with the travel detection system. The two decks are disposed on the double-rail tracks and run appositively at the top and bottom of the outer and inner tracks, two vehicles run on one rail, and the rail mounting posts just need to be mounted above a green belt; the energy-saving double-rail double vehicle conveniently runs, is energy saving and emission reducing, has no effect on jamming urban streets and allows the urban traffic jam to be greatly relieved.
