"Compared with the ordinary urban rail line, the urban rail express line has fast operation speed, large station spacing, large capacity, convenient transfer, and wide service range. The maximum operating speed can reach 140 km/h, which can meet the needs of different passenger flows and improve transportation. Efficiency." According to Wang Meng, chief engineer of Chongqing Railway Group, the urban rail express line 15 is 71.53 kilometers long and will be constructed in phases one and two.
