Aufseßplatz

An unused tunnel stub for a connection curve exists south of the station on the side of the north-bound track. This curve was meant as connection to another subway line from Plärrer to Dutzendteich, which never got beyond an early planning stage. Like Plärrer, Hauptbahnhof and the much later Friedrich Ebert Platz orange tiles were used to indicate a possible interchange station. However, as of 2020 only Plärrer and Hauptbahnhof actually are interchange stations between different subway mainlines.
