Alt-Tegel (Berlin U-Bahn)

Even though line U6 only opened in 1923, by the 1930s there were already plans by the city of Berlin to extend the U6 to Wedding and to Tegel. Construction work for an extension began in 1929 on Müllerstraße. Due to the imminent global economic crisis and the resulting financial consequences for the city of Berlin, the work stopped. The result was a roughly 400-meter-long tunnel.

After the Second World War, the BVG planned an extensive expansion of the Berlin U-Bahn. In the first stage, line C (U6), which then ended at Grenzallee and Seestraße. Construction began for an extension to Tegel on 26 October 1953. The extension was done in two stages. First, the section Seestraße - Kurt-Schumacher-Platz, followed by the part above ground section Kurt-Schumacher-Platz - Borsigwerke then underground to Alt-Tegel. The second section included the stations Scharnweberstraße (above ground), Seidelstraße (now: Otisstraße, aboveground), Holzhauser Straße (above ground), Borsigwerke (underground) and terminus Tegel, which was also underground.

In 1995, when the S-Bahn line to Henningsdorf was reopened, the U-Bahn station was renamed Alt-Tegel to avoid confusion with the S-Bahn station Tegel .
