The Stadtbahnhof survived WWII intact, but came to lose its pre-war significance due to the division of Berlin; with Lehrter Bahnhof closed, the Stadtbahnhof served only a relatively underpopulated area near the border with East Berlin. It was the final stop in West Berlin; the next station, Berlin Friedrichstraße, was in the Soviet zone, although it served as a stop on the West Berlin S- and U-Bahn systems; these parts of the station were sealed off and inaccessible to East Berliners. The S-Bahn, like the mainlines leading to West Berlin, was run by the East German railway, the Deutsche Reichsbahn. The 1961 construction of the Berlin Wall further isolated the station, and led to a boycott of the S-Bahn in West Berlin that lasted until the 1980s, when operation of the West Berlin S-Bahn lines was transferred to the West Berlin transit authority, the BVG.
