[2] It is located at the prosaic western end of the Kurfürstendamm, one of Berlin's most famous and important boulevards and near the lake Halensee, after which the small locality of the city and the station take their names.

To the north of it, two platforms were built for the Ringbahn and the trains were routed from here to and from the Stadtbahn via a newly installed connecting curve.

At the same time, the name was changed to the current Halensee, while the nearby Hundekehle station on the Wetzlar Railway was renamed Grunewald.

The four-track turning system connected to the south, and the Stadtbahn and Ringbahn railways were separated north of the station.

According to Hitler's plans for a "world capital Germania" drawn up in the 1930s, the Ringbahn was to be fundamentally redeveloped.

During the Second World War, the entrance building was hit in Allied air raids and then burned down.

Just four days after the Wall was built on 13 August 1961, a boycott of the S-Bahn was announced by the German Trade Union Confederation and Governing Mayor Willy Brandt.

The campaign met with great approval early on and around 400,000 passengers turned away from the S-Bahn, although the traffic of East German citizens crossing West Berlin and now no longer being used was also a cause.

From May 1977 until the strike in 1980, train group C ran between Zoo and Sonnenallee (previously from Gesundbrunnen) during peak hour.

Due to the drastic decline in passenger numbers, the Reichsbahn was increasingly forced to scale down operations.

However, thinning out the timetable alone was not enough to compensate for the annual deficit of 120 to 140 million Marks (adjusted for purchasing power in today's currency: around €159.4m).

The signal box was not cleared until 22 September when the railway police, which consisted of West Berlin Reichsbahn officers and British soldiers, acted.

The Ringbahn was then shut down and operations were only maintained on the Stadtbahn along with the north-south tunnel and the adjacent routes.

The reversing system in the south, on the other hand, was reduced to just one track, as the new line runs through the remaining area.
