However, I went here for another reason – to visit the shortest (today, not at the time of making the photo, when U55 was still a thing) U-Bahn line in Berlin – U4. In 1903, Schöneberg, south-west of Berlin, planned to develop an underground railway line to improve public transportation and so this line, a short line (2.86 km, 5 stations) just for Schöneberg was finished in 1910.
