However, further extensions in 1908 branched off at Deutsche Oper straight westwards to Reichskanzlerplatz (today Theodor-Heuss-Platz) and the affluent Westend area, so the track to Wilhelmplatz remained a stub.

A short-distance train from Deutsche Oper served the station until it was finally closed and demolished in 1970.

The new Richard-Wagner-Platz station opened on 28 April 1978 with the extension of the U7 line from Fehrbelliner Platz.

It features several Byzantine style mosaics of medieval historic figures, the decoration from a former hotel near Potsdamer Platz that had been demolished in 1975.

As the old tunnel has been preserved there is still a direct connection to the U2 at Deutsche Oper, used solely for maintenance purposes.
