Third rail
A first station named "Grunewald" south of the present platform opened on 15 November 1877 at the western Ringbahn railway line. It was shifted toward the Kurfürstendamm a few years later and reopened on 15 October 1884 as "Halensee", including a Neo-Romanesque entrance building, while the present Berlin-Grunewald railway station received its name. Third rail S-Bahn service commenced on 6 November 1928. The entrance hall was heavily damaged by air raids in World War II and finally demolished in 1958.
