Tracks north of Guangyang Cheng station

The Fangshan Line starts at Yancun Dong (E), just west of the East Yancun Bridge, where it interchanges with the Yanfang Line. Previously, it started at Suzhuang which is located at the intersection of Changhong Xi Lu and Suzhuang Dajie in the Liangxiang area of Fangshan District. The line makes four stops in Liangxiang including at the Fangshan Campus of the Beijing Institute of Technology. The line then heads north to the towns of Guangyang and Changyang. After crossing the Yongding River, the Fangshan Line enters Fengtai District where the line makes two more stops, at Dabaotai near the Beijing World Park, and at Guogongzhuang, also the southern terminus of Line 9. The line furthermore makes four stops northeast.

Construction of the Fangshan Line was originally set to begin in 2012[5] but was moved up to April 1, 2009 to use stimulus funding provided by the government to counter the Financial Crisis of 2007-08.[6] The names of Phase 1 stations was announced on March 25, 2010 as a 7-day publicity.[7]

On December 30, 2010, the line began operating from Suzhuang to Dabaotai, but was not connected to any other line of the subway system. One year later, on December 31, 2011, the Dabaotai to Guogongzhuang section opened, linking the Fangshan Line with Line 9 and the rest of the subway network.

On December 30, 2017, the line was extended one stop westward to Yancun Dong (E).

On December 31, 2020, the line was extended north by 4 stations.[3]
