History
Line 12's route has undergone substantial changes on the planners' drawing board.
In the late 1990s, one draft of the subway plan showed Line 12 running from the Beijing South railway station to Huangcun.(Chinese) [http://www.ccmetro.com/newsite/readnews.aspx?id=4387 新闻行业资讯正文精彩关注北京地铁规划一览] {{webarchive|url=https://web.archive.org/web/20101120094942/http://ccmetro.com/newsite/readnews.aspx?id=4387 |date=2010-11-20 }} Feb. 2, 2004 The Beijing South railway station was then built with subway platforms for only Lines 4 and 14. The old plan of Line 12 is cancelled now.
A new plan of Line 12 was announced at January 2012.(Chinese) [http://zhengwu.beijing.gov.cn/gzdt/bmdt/t1213294.htm "2015年轨道交通长度达708公里 4条“增强版”地铁线2012年开建" 《北京日报》] {{Webarchive|url=https://web.archive.org/web/20170920213118/http://zhengwu.beijing.gov.cn/gzdt/bmdt/t1213294.htm |date=2017-09-20 }} 2012-01-13 In June 2012, there were several media reports listing the planned stations of the line. The final planning of the line started from Sijiqing in Haidian District east to Guanzhuangluxikou in Chaoyang District, following the northern Third Ring Road.(Chinese) [http://www.bjnews.com.cn/news/2012/06/16/205055.html "北京将再增3条新地铁" 《新京报》] 2012-06-16 The entire line has 21 stations, of which 15 will have transfers with other lines.{{Cite web|url=http://finance.people.com.cn/n1/2018/0112/c1004-29761240.html|title=北京地铁12号线预计2021年通车 换乘站达15座--财经--人民网|website=People's Daily|access-date=2018-02-10}} The line will provide relief for the northern arc of the congested Line 10 loop line.
