Also, I don't know of us generally calling something a "tube station", we call the network the underground, and after that pretty much refer to the different lines. So if you want to refer to the signage or getting directions from Brits, y'know. The signs don't say "tube station" or "underground" either as far as I recall from my last train journey. You get the main sign outside the station saying "Waterloo East" or whatever, then inside signs directing you to Northern Line, District Line, Circle Line etc.
So you could refer to the places as Victoria Station, I reckon, since it is a place, or just Victoria. But you wouldn't necessarily need to call it London Victoria Underground, near London Victoria coach station
