What is it like to travel by train? Is it on an average, expensive? Comfortable? Are they ever overcrowded with passengers? What are the lavatories like? Does the train make layovers so that you can browse around a bit? Is the food good? Have you ever been disappointed and why? What's the shortest or longest trip that you've taken? I ask these questions because I would like to take a trip on a train just for the experience. Everyone I know travels by plane or does road trips. I like to hear of someone's experiences, especially if it was your first trip on a train.
