PHOTO GALLERY: RÜMMLER’S U7
THE U7 IN its current form was largely a product of Cold War-era West Berlin, and is arguably the most “West Berlin” of all U-Bahn lines. Despite being Berlin’s longest U-Bahn line (as well as one of the longest underground urban rail lines in all of Europe at 31.8 kilometers), every single one of its stations, from Rudow in the southeast to Rathaus Spandau in the northwest, falls within the borders of the former West Berlin.
