Maybe I’m a romantic but traveling through Europe by train is just lovely. Seeing the different regions and towns is so beautiful, I studied English literature and Art History so I’ve read about writers and painters hopping on the train to work on their next project. I can see where they find the inspiration as trains pass through these idyllic towns and pull into different train stations.
Whenever possible, buy train tickets in advance for the cheapest rates and go for the flexible tickets. I have had flight delays mess up travel plans and all sorts of mishaps. The one upside to having flexible tickets is the ability to move my plans around.
Know your seat assignments when you get on the train. I can’t keep track of how many times, I’ve gotten on and taken my seat only to watch other passengers squabble over seats because someone mistakenly sat in the wrong seat. It gets even more interesting with language barriers. It’s always an honest mistake but I recommend the window seat and think about the direction the train is headed. I take pictures and sometimes film parts of the journey if it’s especially scenic. If you end up with a bum seat, you’re missing out.
