Description

Technical Field

[0001] The present invention relates to the technical field of rail transit, and in particular to an urban rail transit double-line four-row parking wiring system and an operation method thereof. Background Art

[0002] When two stations with temporary parking facilities are located too far apart on urban rail transit lines, stop lines should be established based on operational needs and engineering requirements. These lines are primarily used to temporarily park faulty trains, allowing them to be promptly removed from the line and withdrawn from service. They can also serve as temporary reversing lines, allowing faulty trains to return to the depot at any time, creating flexibility for daily operations. They can also be used to park vehicles at night. When vehicle bases are located far apart, using stop lines at intermediate stations to park vehicles can delay morning rush hour departures, reduce vehicle mileage, and save operating costs.

[0003] According to current technology, when rescuing a faulty train, the trains on the front and rear stop lines affect each other, making operations inflexible and requiring reverse end switching and communication operations. Therefore, the rescue time of the faulty train is relatively long, which will affect the normal operation of subsequent trains in the same direction, causing them to slow down or stop at stations in advance, which has a greater impact.
