I did a mistake. The train from Prague to Hamburg, which I am on, is overcrowded and I just grabbed the first seat I could find. Then, I checked the reserved list, and realized that my seat is reserved from Dresden to Berlin. When I checked the map, I saw that Dresden is pretty close to Prague. The seat next to mine is not reserved at all. I should have checked before sitting down, and not just gone for the seat closest to an electricity outlet. Well, I guess I’ll have to sit in the corridor once we reach Dresden. That is also part of the Interrail experience.
I think I might get similar problems on all the trains I’m supposed to catch today. I just realized it’s Friday, and a lot of people are probably going to Berlin or Copenhagen for the weekend. It’s going to be a long day.
