Shijingshan District
Although officially a defunct railway station (thus having no subway code number), Heishitou station () is often considered a disused station on Line 1 by the general public, probably due to its location on a disused China Railway military-only branch line which happens to link to line 1. There are two side platforms with space for two tracks. The (unofficial) name of the Heishitou station is derived from its proximity to the nearby Heishitou Village located in Shijingshan District, Beijing, in the Western Hills. There is a secret bunker-like facility used as an underground command centre by the Chinese military dating back to the 1950s (similar to the Pentagon), thus rendering this part of the Western Hills inaccessible to the public.
