However, one could also argue that the majority of the nation does not have the luxury to spend a single day traveling, so going by sleeper train is even better. I recently had a business trip to Switzerland and took the sleeper train from Berlin to Basel (9pm to 8am) where I arrived after a nice breakfast (in the train) so much more relaxed than after a hectic flight. Its more expensive but only because its basically hotel + trip.

Right, but the equivalent of trains that take multiple days are sleeper/red-eye flights of 5+ hours during which many people can catch up on some sleep.

I've taken that train as well and while it's nice for routes of around that distance, I'm not sure how it would be beneficial if you had to sit on it for days. That wouldn't be much of a sleeper trip.
