If you are traveling in Baden-Württemberg, then a stop at the Karlsruhe train station will be almost inevitable, since this is the junction point of the Rhine Line and lines leading to France and Bavaria. The building of the station itself, built in 1913, is somewhat gloomy, but everything is thought out perfectly inside: ticket purchase, service, food, logistics. I especially love the yellow Deutsche Bahn timetable. Logical, intuitive, rhythmic. With the only drawback now: trains often do not adhere to it...
