 The opening of the Potsdam Hauptbahnhof (now Potsdam Pirschheide Station) in 1956 and the establishment of the Berlin Wall on 13 August 1961 meant that the Potsdam city station (now Potsdam Hauptbahnhof) lost most of its passengers.Only a limited service ran between Werder and Potsdam Babelsberg, and a few trains ran to Jüterbog.With the opening of the border in 1989 and the renovation of the Berlin Stadtbahn in 1997 traffic flows changed substantially and by the BAR platforms on the upper part of Pirschheide station are now no longer served by passenger trains.
