As always, BoingBoing finds some great links. Mark posted a link to this 1997 article Mysteries Under Moscow, which I’d seen a few years ago, but is still very interesting. Much more about moscow underground at metro.ru, which is a comprehensive site about the Moscow Metro. It’s simply a great site. (Translate it translated into English with Babelfish).
