The Americans are Winning

Being out of England for most of the time, I tend to notice small changes when I'm there that may be imperceptible to those who live there. One of these is the creeping Americanisation of the English language. Not only do we have a whole generation who use American spelling because they've never bothered to change the default spell checker in Word to British English, but American vocabulary is gradually replacing British usage.

One of the changes I observed on this year's visit is that the original British "railway station" has largely given way to "train stati0n", which in my childhood would have been understood but considered an Americanism. Now that usage makes sense, since "bus station" was already common British usage, but why don't we call an airport a "plane station" to be consistent?
