with Bundesallee. It then follows Hohenzollerndamm to Fehrbelliner Platz, which provides interchange with the U7, and continues south under Barstrasse. Below street level, the U3 crosses the Fennsee (lake) in Volkspark Wilmersdorf (park) on a two-level bridge. Beyond the A 100 and after passing under the Ringbahn at Heidelberger Platz it follows the streets of Aßmannshauser Straße, Rüdesheimer Straße and Schorlemerallee and leaves the tunnel immediately before Podbielskiallee station. From there, the U3 continues in a cutting next to Archivstrasse and later Brümmerstrasse. Passing behind Freie Universität (Thielplatz), it turns due west. The last section runs south of the streets of Saargemünder Straße and Argentinische Allee. The U3 terminates at Krumme Lanke station, named after a nearby lake, at the intersection of Fischerhüttenstraße and Argentinische Allee. History In the summer of 1907, the Hochbahngesellschaft ("Elevated Railway Company") of the new town of Wilmersdorf proposed the construction of an underground railway through the area. A route was envisaged running to Nürnberger Platz and, if Wilmersdorf would pay for it, on to Rastatter Platz, now Breitenbachplatz. Since Wilmersdorf had poor transport links, this suggestion was readily accepted. The commission for the development of the lands of Dahlem Manor, which were further south and were still largely undeveloped, was very interested in a rail connection. It wanted the proposed line to continue from Breitenbachplatz to Thielplatz. Now, however, a big problem arose. The proposed line would run partly through Charlottenburg, but the municipality of Charlottenburg saw Wilmersdorf as a major competitor when it came to attracting wealthy taxpayers. Long negotiations were conducted until the following agreement was finalised in the summer of 1910: in addition to the line already planned, another one would be built in Charlottenburg under Kurfürstendamm with the provisional terminus at Uhlandstraße. According to one source, the then Prussian Minister of Public Works, Paul von Breitenbach, is said to have directed the city of Charlottenburg to allow the construction of the Wilmersdorf U-Bahn. As a result Rastatter Platz station and the square it was named after before the opening of the U-Bahn was renamed Breitenbachplatz by the grateful city of Wilmersdorf. Construction work began in the summer of 1910. The following stations had to be built or converted: Wittenbergplatz (conversion) Nürnberger Platz (now closed) Hohenzollernplatz Fehrbelliner Platz Heidelberger Platz Rüdesheimer Platz Breitenbachplatz (originally planned as Rastatter Platz) Podbielskiallee Dahlem-Dorf Thielplatz (temporary terminus, then having a small waiting room) as well
