After many years of declining passenger use and difficult industrial relations between the West Berlin workforce and their East Berlin employers, most of the western portion of the S-Bahn was closed down on 11 September 1980 following a strike.
Setelah beberapa tahun mengalami penurunan jumlah penumpang dan kesulitan hubungan industrial antar pekerja Berlin Barat dan Jerman Timur, sebagian besar bagian barat dari S-Bahn ditutup pada bulan September 1980 karena sebuah pemogokan.
