When a train comes to a big town, it is "in" it. When it passes through a small town, it is, briefly, "at" it.

It depends. Are we discussing when the train entered the city proper? Then "in" would be accurate. If we're discussing a specific stop called "London", then I would say "at".

I think you're all missing the obvious inaccuracy with the statement: a train arriving in London only 10 minutes late? Ridiculous - they're always at least 20 minutes late!
