In 2006, Line 11 was originally designed as an L-shaped line from Wanliu to Dahongmen, which together with the L-shaped Line 10, form a subway ring route.[1] After Line 10 Phase II took over the entire ring route, Line 11 was displaced.
In January 2010, the government of Shijingshan District disclosed plans for a Line 11 in western Beijing that would traverse the Beijing Capital Steel complex and intersect with Lines 1 and 4.[2]
