Architect Alfred Grenander planned a station featuring three tracks serving a branch-off toward eastbound Große Frankfurter Straße that was never built and in 1930 was replaced by the U5 line.
The billboards, which were not needed in GDR times, provided space for a total of 22 enamel panels from the Schilderwerk Beutha, which depict the development of Berlin's public transport system on the basis of the respective vehicles.
In addition, the front part of the railcar 12 of the Schoeneberg Underground from 1910 was restored to its original state and placed in November 1985 at the northern end of the platform between the two stairs.
After the U2 in the context of German reunification at the end of 1993 was again passable, the tunnel lost in importance, since the small profile vehicles could now be maintained in the workshop Grunewald.
Spokesman Dieter Wendt now walked back the way and then through the streets of Berlin to the subway station Jannowitzbrücke, where he enlisted for necessary work on the track.
