Abandoned subway stations are subway stations that are no longer used. They may still have subway trains that pass through without stopping, or they may be on a portion of the subway line that is no longer in operation (or never was). Abandoned subway stations may be hideouts, they may be haunted, or they may be beast dens. In modern fantasy worlds, abandoned subway stations may be in use by magic users or magical beings and may part of a hidden route that links to a hidden location (a hidden market or a hidden town for instance) or connect to a different magical realm.
