Sorry, I forgot that a subway station does not always have to be under 

Tagging an above-ground subway station as a building is common practice. 
For underground buildings, things are more difficult; we don't have an 
established way of recording the fact that they are below the surface. 
layer=-1 doesn't cut it as it is only relative to other features, not 
relative to the surface; and tunnel=yes doesn't sound right either (a 
subway station is not a tunnel, and is not usually "in a tunnel" either).

For this reason, most renderings will look shite with underground 
buildings, and even non-rendering uses will draw the wrong conclusions 
from a subterranean subway stations being tagged as buildings.

But then again, the underground buildings are those for which knowing 
the location of the entrance is most useful because you cannot simply 
walk around them until you find one ;)
