Западный Берлин
In 1948–1952, the Reichsbahn connected the western suburbs of West Berlin to its S-Bahn network. Train routes servicing these suburbs formerly went through West Berlin stations, but ceased to make stops in the western stations or terminated service before entering West Berlin. Private West Berlin railway lines like the Neukölln–Mittenwalde railway (Neukölln-Mittenwalder Eisenbahn, NME), connecting the East German Mittenwalde with West Berlin-Neukölln and the "Bötzowbahn" between West Berlin-Spandau and East German Hennigsdorf, were disrupted at the border between West Berlin and East Germany on 26 October 1948 and August 1950, respectively.
