The new line is operated by Beijing MTR Corporation, a joint venture between MTR Corporation, Beijing Capital Group, and Beijing Infrastructure Investment Corporation which already runs Line 4 and the Daxing Line.

The initial phase has seven stations, including Garden Expo Park (pictured), which will serve the 9th China International Garden Expo due to start on May 18.

Civil works began in 2010 and the line was built by Beijing Infrastructure Investment Corporation. Beijing MTR is responsible for electrical and mechanical systems as well as rolling stock under a PPP concession signed last November, which includes a 30-year operating term. This contract is worth around Yuan 15bn ($US 2.4bn), about 30% of the total cost of the project.

When it is completed in 2016, Line 14 will stretch for 47.3km along the southern edge of Beijing with 37 stations, linking Zhanggouzhuang in the west with Shangezhuang in the eastern district of Chaoyang.
