The Tränenpalast is a former border crossing point between East and West Berlin, at Berlin Friedrichstraße station, which was in operation between 1962 and 1989. It is now a museum with exhibitions about Berlin during the Cold War period and about the process of German reunification. It was the border crossing for travellers on the S-bahn, U-bahn and trains going between East and West Germany. It was used only for westbound border crossings.
