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) 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; Phase I is now designated as Line S1 of the city's metro system, and the under-construction extension is designated as Line S9.

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. The line started construction on December 27, 2011, and was opened on July 1, 2014.

A future extension of the line will start from Xiangyulunan station; the 6th station from Nanjing South railway station, and extend further south, to Gaochun District, for the total length of 85.8 km.

In September 2011 a contract for 15 6 car Type B metro trains was given to CSR Corporation Limited, with the first train arriving in August 2013.
