I already had a train travel experience. At first I thought it would be boring and tiring. That's because I imagine that the train would be slow, noisy, or worse, crowded with people stuck together, sweating and making the place extremely stuffy, but I had an entirely different and pleasant experience.
The train I took was not a commercial train, but a train that featured a sightseeing tour in a city next to mine. The train was not crowded with people, allowing everyone to sit and feel comfortable. The relative "slowness" that the train presented was a good surprise since it allowed us to enjoy the view and the noise that the train made stopped bothering minutes after the journey started.
