Beijing Metro Directory

Many thanks, temppeternh!

Very comprehensive list.
Note that "Xī Zhí Mén 西直门 (Lines 2, 4, & 13; S2 suburban railway [temporarily suspended])" - is no longer true the Beijing North Railway station has reopened a short while ago. On a related topic, I also don't see the Qinghe station that is connected to the Qinghe Railway station.
I did not do an exhaustive check but was looking for these two that are useful for tourists.
