The Nanjing–Gaochun Intercity Railway, commonly known as the Ninggao Intercity Railway (Chinese: 宁高城际轨道交通; pinyin: Níng gāo chéng jì guǐdào jiāotōng[Note 1]) or Airport Line is a suburban metro rail line serving the southern suburbs of Nanjing. In early planning documents, it was called Line 6 of Nanjing Metro; now it is designated as Line S1 of the city's metro system.

The Ninggao Line's first stage connects Nanjing South Railway Station with Nanjing Lukou International Airport. It is 34.9 km long has 8 stations.[2] The line started construction on December 27, 2011,[3][4] and was opened on July 1, 2014.

A future extension of the line will start from Lukou New City North Station (禄口新城北站; the 6th station, counting from Nanjing South Railway Station), and extend further south, to Gaochun District, for the total length of 85.8 km.[5]
