 After the erection of the Berlin Wall in 1961, West Berliners boycotted the S-Bahn to put pressure on the GDR government, which controlled the parent Deutsche Reichsbahn.The boycott led to extremely reduced S-Bahn passenger numbers, and after a strike by West Berlin S-Bahn employees to the ending of service over large stretches of the system in the West.The West Berlin portion of the Ringbahn, including the Tempelhof station, was taken out of service in September 1980.
