You see, just by boarding a train, one could reach another country in a few hours. Sure, I went to Poland and back a couple of weekends ago, just for 29 EUR. Then, I also went to Göttingen and back, and on the way back, my train originated from Basel, Switzerland. There is a night train to Paris. The Berlin-Warsaw train runs a few times a day.
I guess this is what I love about Europe. The connectivity. The efficiency. The streamlined train system. Amtrak is a far cry from the standards here in Europe. So whenever I ride the short-distance commuter trains and see an ICE zoom by, my brain goes into daydreaming mode, and see what cities I might be able to visit, just by riding this train.
