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) 新闻行业资讯正文精彩关注北京地铁规划一览 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.
