The invention relates to a double-layer running
urban rail transportation
system, which mainly consists of trains, a
station,
stairs, bridge piers, rails, connecting plates and a current collection rail, wherein the bridge piers are arranged at both sides of a cycle path, the rails are erected at the top ends of the bridge piers, the trains run along the upper layer and the lower layer of the rails, the upper layer and the lower layer are non-interfering with each other, the double-layer running and the directional passing are realized, a suspension type
train runs at the lower layer,
train wheels run in grooves under the rails, the
station is fixedly arranged on the bridge piers, the two sides of the rails are provided with an upper
pedestrian path and a lower
pedestrian path, the
station is connected with the ground by the
stairs, and passengers go up to the
pedestrian paths at the two sides through elevators or the
stairs around the bridge piers, so as to get on or off the double trains. The transportation method has the advantages that the structure is simple, the manufacturing cost is low, the convenience is provided for the passengers, safety and stability are realized, and meanwhile, the space above the road can be sufficiently utilized.
