When the Berlin Wall was erected on 13 August 1961, it had a profound effect on rail services in and around the city, and on the S-Bahn and U-Bahn in particular.
After the fall of the Wall on 9 November 1989, Anhalter Bahnhof S-Bahn station and all the ghost stations underwent a major refurbishment before being re-opened on 1 March 1992.
