Trains allow you to travel in safety and comfort and their charm sets them apart from more mundane means of transport. They pollute less, rarely suffer from weather delays and won't give you jet lag. You can talk to your companions, read a book, or have a snooze. If you tire of the scenery you might go for a stroll, have a meal in the dining car, make friends in the bar or watch a movie.
