"Disculpe, señor, ¿dónde está la estación del metro?"
Translation:Excuse me, sir, where is the subway station?
As an Aussie, I just put "train station." I don't know that they are much called "subway stations" or "tube stations here."
"Subway station" is used when referring to underground trains, such as those in London and New York. I have also heard British people say "metro" in movies, when they are speaking about the London subway. Train stations are usually above ground, but if I were in NYC and heard somebody say, "I'm going to take the train," I would know what they meant even if I knew that they meant the subway.
