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.[2] The Beijing South Station was then built with subway platforms for only Lines 4 and 14. As of January 2012, Line 12 was under preliminary planning and is slated to run from Tiancun in Haidian District east to Dongba in Chaoyang District, following the northern Third Ring Road.[3]
In June 2012, there were several media reports listing the planned Line 12 stations.[4]
