The first phase of Chengdu Metro Line 10 is Chengdu’s first dedicated metro line to serve airport passenger flows. It is a significant project to connect aviation hubs, enhance the city’s image, and create an international metropolis. The line connects the main urban area with Chengdu Shuangliu International Airport. It realizes the "zero distance" transfer between air transportation and metro transportation. As an urban express line serving the main urban area of Chengdu and the Xinjin zone, the second phase of Chengdu Metro Line 10 will fundamentally change the passenger flow and commercial flow patterns along the line, lead and change the urban development pattern, and accelerate the realization of magnificent picture of "High-speed rail hub, Full rail coverage, Metro City".
