In filming the station Potsdamer Platz on the U2 line in the summer of 2000, restored in the nineties after it had been closed for almost three decades during the Cold War. Note the special skylights and chimney, with mirrors that follow the motion of the sun, allowing illumination of the underground station with natural light.
same movie station Koch Strasse, U6, near the old checkpoint Checkpoint Charlie, who separated the U.S. from the Soviet sector.
For nearly three decades, from 1961 to 1989, the city of Berlin was divided in two by a wall, "the wall" that separated the area occidendale, West Berlin, from the east, East Berlin
The subway, U-Bahn (Untergrundbahn, underground railway), and the suburban network, S-Bahn (Stadtschnellbahn, suburban and urban railways), suffered a similar division lines could be used only by those who lived in West Berlin and lines only for those who lived in East Berlin
Some lines (those from west to east) were broken into two sections, one western and one eastern. The S3 line was stopped at the station Friederichstrasse, in the east, while the line was cut between stations U2 Gleisdreieck, in the west, and Kaiserhof, Mohrenstraße present, in the east. In the eighties the West stopped suddenly was replaced by a line magnetic levitation experimental M-Bahn.
Other lines (those from north to south), as the two metropolitan and suburban U6 and U8 S2, which had their terminus in the western sector were not interrupted, although they crossed their path in the central stretch of the east.
To prevent the transit of passengers between the two sectors all stations belonging to the relevant portions were sealed and placed the trains do not stop there: this became known as "ghost stations" (Geisterbahnhöfe).
Among these stations, to Friederichstrasse, was an exception, because even though in the eastern sector was fully accessible to passengers but the only Western transfer line S3, which made them terminus after truncation, the line S2 and U6 , passing through.
ghost at all stations was 16.

station Friederichstrasse ghost was not because it was open on both the western lines S3, S2 and U6 that on the remaining eastern section of the S3 but it was not possible for direct transit passengers from one area to another (there was a check-point control).
In the YouTube video taken from the station Bernauer Strasse ghost seen by a convoy to the station Voltastraße on the U8 line, in the autumn of 1989, just weeks after the fall of the wall.
