> People take the train in the same situations when they drive a car
Not always. I live on the south coast of the UK. If I had to get to Scottish cities such as Glasgow (450 miles) or Edinburgh in a single day's journey I would fly or take the train, but never consider driving - it would be an absolutely horrendous car journey (edit: at least 8 hours assuming perfect traffic).
It is the point. People in Europe very much do consider train vs. plane. I encountered this first hand in personal considerations, family vacation planning and in a policy handout in a big corporation.
Quite a few of my friends in Europe prefer not to fly for environmental reasons as well, which I don't see really discussed a lot here. Oftentimes flight is seen as a last resort mode of transportation.
Not in Eastern Europe and the Balkans where trains and rail infra are crap. If I were going from Austria to the Czech Republic, sure. Hungary to Greece? No way.
