On 13 August 1961, with the construction of
Berlin Wall, S-Bahn traffic from Stahnsdorf and Potsdam was discontinued. The only occurrence is that there is only Potsdam-Griebnitzsee shuttle until it was discontinued in 1962. Residents commuted only to East Berlin via the longer
Berlin outer ring from Potsdam through regional express trains, and the only trains running on the
Berlin–Magdeburg railway was transit traffic from the West Berlin via the GDR to West Germany and other countries. Later on, after the
fall of the Berlin Wall, the line was re-connected to Potsdam again. Reconstruction began in April 1991 and was completed on 1 April 1992. Between the fall of Berlin Wall and 1 April 1992, Potsdam was connected through the fastest way via Griebnitzsee to interchange at Wannsee, besides transit traffic. S1 was temporarily extended from Wannsee to Potsdam Stadt from 2003 to 2006. S-Bahn line
S1 terminates at Wannsee, and operates to and from central Berlin via the
Nord-Süd-Tunnel. Line
S7 passes through Wannsee on its route to
Potsdam Hbf, and operates to and from central Berlin via the
Stadtbahn. The two routes to central Berlin diverge by way a
flying junction between Wannsee and
Nikolassee stations. The station entrance building lies to the north of the station, and is linked to the platforms by a subway. To the south of the entrance are two island platforms used by the S-Bahn services, and then a single longer island platform used by Deutsche Bahn and Veolia trains. The AutoZug terminal is to the south of the station. ==Train services==
