"The train network under the streets is so dense I can go anywhere on it, popping out of the earth in one place or another. It is a skein of arteries, pumping people around the city."

This film gives a sense of how punctual, quiet, empty and efficient the Berlin U-Bahn system is.


Filmed in the GDR, this records a journey on a West Berlin train as it bypasses Bernauer Strasse – a Geisterbahnhof (ghost station) – as it travels briefly into East Berlin, before stopping at Voltastrasse, a station back in the west. This map, showing where the Wall once stood, makes it clear why this happened.
