Ghost station

Ghost stations is the usual English translation for the German word Geisterbahnhöfe. This term was used to describe certain stations on Berlin's U-Bahn and S-Bahn metro networks that were closed during the period of Berlin's division during the Cold War. Since then, the term has come to be used to describe any disused underground station actively passed through by passenger trains, especially those on an underground railway line.

In August 1961 the East German government built the Berlin Wall, ending freedom of movement between East and West Berlin. As a result, the Berlin public transit network, which had formerly spanned both halves of the city, was also divided into two. Some U- and S-Bahn lines fell entirely into one half of the city or the other; other lines were divided between the two jurisdictions, with trains running only to the border and then turning back. However, there were three lines—the U-Bahn lines now designated U6 and U8, and the Nord-Süd Tunnel on the S-Bahn—that ran for the most part through West Berlin but passed through a relatively short stretch of East Berlin territory in the city centre. These lines continued to be open to West Berliners; however, trains did not stop at most of the stations located within East Berlin, though for technical reasons they did need to slow down significantly while passing through. (Trains did stop at Friedrichstraße, on which more below.) The name Geisterbahnhof was soon aptly applied to these dimly lit, heavily guarded stations by travelers from West Berlin, who watched them pass by through the carriage windows. However, the term was never official; West Berlin subway maps of the period simply labelled these stations "Bahnhöfe, auf denen die Züge nicht halten" ("stations at which the trains do not stop"). East Berlin subway maps neither depicted the West Berlin lines nor the ghost stations. U-Bahn maps in the Friedrichstraße transfer station were unique: They depicted all the Western lines, but not the Geisterbahnhöfe, and showed the city divided into "Berlin, Hauptstadt der DDR" ("Berlin, capital of the German Democratic Republic") and "Westberlin."
