It was so exciting as a young kid being driven on to a train, travelling under the sea, then in 30 minutes being in a different a totally different country - France - with a different language, time zone, currency, etc! It even smelled totally different. Then continuing the journey around Europe, there were even more currencies and more languages and different cuisines. Ah the nostalgia!
