From 1951 until the building of the Berlin Wall, services continued past the city limits to nearby Teltow.

Together with Osdorfer Straße station, this connects the Thermometersiedlung high-rise housing estate to the Berlin S-Bahn network.

The original desire to extend suburban operations to Lichterfelde, however, was not met and traffic was limited to a few long-distance trains.

Under the Greater Berlin Act of 1920, the borders of the capital was moved to just south of Lichterfelde Süd.

In the Nazi era, as part of the planning for World Capital Germania, an extension of the suburban line via Lichterfelde Süd and Teltow to Trebbin was planned along with a new line to be built from Lichterfelde Süd to Stahnsdorf to link there with the Cemetery Railway to Wannsee.

The freed-up capacity meant that a long-distance track was now available to be electrified and upgraded as an S-Bahn line to Teltow.

Shortly after the border was closed, the line was reopened but only for a single movement, as an S-Bahn train had been stuck in Teltow when the wall was built.

The railway facilities remained unused and deteriorated, although the administration building was later converted into a dance hall.

After the reunification of Germany, it was agreed that the Berlin S-Bahn network would be restored as far as possible back to the condition of 1961, so the re-opening of the Anhalt line was expected.
