How about 'tube' instead of subway i.e. British vs American
You are right. I didn't think enough about the context. Anyway I associate the word "by" mostly with town here in Norway :)
I used "town" in stead of "city". Should be OK too.
We accept "town". But city is probably the better translation in this case as places with a metro are usually pretty big.
T-banen does not show orange (for introducing a new term)
Why is 'underground' not correct?
