 After the September 1980 strike of West Berlin S-Bahn workers, the Reichsbahn almost completely closed the S-Bahn in West Berlin, including the Ringbahn.The Neukölln - Mittenwalde line, in contrast, profited from increased goods traffic after the West Berlin power company, Bewag, built a power plant at Rudow.Within the city, its passenger stations were demolished, while outside the city, in the GDR, the rails were taken up but the station buildings remained.
