U1

A train on Berlin's U-Bahn line U1

The U1 is Berlin's oldest U-Bahn line, with the oldest section - built on a viaduct running westwards from Warschauer Straße along the course of the 19th century city walls - first opened in 1902.

Construction Work

From the end of 2007 until late 2008 extensive reconstruction and repair work is being carried out on the U1's above-ground sections. This will involve closure of some sections of the line. Currently the section between Wittenbergplatz and Gleisdreieck is not operating: see here for further details.

History

The section of the U1's route west of Wittenbergplatz has been subject to frequent change. At its inception, the U1 continued from Wittenbergplatz to Ruhleben, a stretch now served by the U2. In 1993, following the reopening of the U2 between Wittenbergplatz and Mohrenstraße, the U1 and U2 swapped their western ends, with the U1 taking over the southwestern line to Krumme Lanke. The reason for this swap is the layout at Wittenbergplatz, which only enables non-conflicting train movements in this configuration.

In 2004 the western part of the route was changed yet again, with the U1 taking over the short stretch of line under the Kurfürstendamm to Uhlandstraße, replacing the now defunct U15. The line to Krumme Lanke became the U3, a line number which had not been used since 1993.
