In fact, it's rare to even use the word "station" in London, we just say, "We'll be arriving at Euston (or Waterloo or Paddington etc)"
If a city or town has only one station, then we do use "station".........
"I'll meet you at Preston station at 5.30".
Incidentally, although more and more people in the UK are using the phrase "train station", correct BrE requires "railway station".
