Line 5 of the Beijing Subway (Chinese: 北京地铁5号线; pinyin: běijīng dìtiě wǔhào xiàn) is Beijing's only subway line with an entirely north-south route. Line 5's color is maroon. It entered into operation on October 7, 2007. It runs for 27.6 km (17.1 mi)[5] in a near straight line through the city center (just approximately one kilometre (0.62 mi) east of the Forbidden City at Dongdan) from Tiantongyuanbei in Changping District to Songjiazhuang in Fengtai District.[6] Though Line 4 and Line 8 also broadly follow north-south routes (and so, in part, do Lines 14 and 13), Line 5 remains the only line to follow an almost entirely straight north-south course. Line 5 is also notable for including three stations in the densely populated northern suburb of Tiantongyuan, as well as providing convenient access to the Temple of Earth and Temple of Heaven. Since Line 5 connects with Line 1, Line 2 (twice), Line 6, Line 7, Line 10 (twice), Line 13, Line 14 and Line 15, and also links densely populated suburbs directly to the city center, it tends to experience very crowded conditions during rush hour and even very late into the evening. Over 1 million passengers use the line every weekday in 2019.[7]

The first south-bound trains departs from Tiantongyuan North at 4:59am. The first north-bound train departs from Songjiazhuang at 5:19am.

Line 5 was the first subway line in Beijing to feature platform screen doors in underground stations and automatic platform gates in elevated stations that prevent riders from falling onto the tracks. Line 5 stations also have LCD screens that display the wait times for the next train. Line 5 trains have digital voice announcements (in Mandarin and English) and LCD passenger information displays.
Construction work on Line 5 got underway in late 2002 and the line opened to the public on October 7, 2007.
