Rail transit system

The invention discloses a rail transit system, which comprises a runway track and a vehicle running on the runway track, wherein the runway track is provided with a first vehicle wheel running face, guide rails and a second vehicle wheel running face which are arranged in a form shaped like a Chinese character 'tu' in turn; the two sides faces of each guide rail are main guide faces; the side faces of the two running faces are provided with side guide faces; the vehicle used in combination has power wheels and guide wheels; the power wheels run on the first vehicle running face and the second vehicle running face respectively; the guide wheels run on the main guide faces and the side guide faces respectively; and wires are arranged on the upper surface of the guide rails. Compared with the currently used straddle type rail transit system, the system has the advantages that: the vehicle body and center of gravity of a used vehicle are low; the accelerating performance and braking performance are high; the turning is smooth; and the running is more stable.
