[0002] When two stations with temporary parking conditions are too far apart on urban rail transit lines, parking lines should be set up according to operational needs and engineering conditions. Parking lines are mainly used to temporarily park faulty trains so that they can be taken off the line and out of operation in a timely manner. They can also serve as temporary return lines to create conditions for faulty trains to return to the depot at any time, creating flexibility for normal operation management. At the same time, parking lines can also be used to park vehicles at night. When the vehicle bases are far apart, using the parking lines of the intermediate stations to park vehicles can delay the departure time during the morning peak, reduce the vehicle mileage, and save operating costs.
