Description

Technical Field

[0001] The present disclosure relates to the field of rail transit, and in particular to a cross-track device and a rail transit system. Background Art

[0002] When the rail transit line is laid on the ground, the wheel-rail guide structure will block the roads that intersect the track. In the related art, an overpass or an underground passage is used for people to pass, but it has a great impact on the surrounding environment. People with disabilities and those carrying large items need to pass through elevators, and the cost is very high. If the passage of social vehicles is also required, the impact on the surrounding environment and the cost will increase further. In addition, in the rail transit vehicle base, the track is usually laid on the ground.
