I have taken the train in many countries, and Germany was one of the weirdest experiences because I expected deutsche Gründlichkeit and got one of the shittiest ticketing machines imaginable, then boarded a train after over an hour of waiting because all trains were delayed, but was told off for having the wrong ticket because it was a direct train and I bought a ticket for the snail train, which I didn’t know was a thing. The train stations were clean though.
