It lies at the opposite end of the Stadtbahn to Ostkreuz and is one of the four main stations on the Ringbahn (circle line).

[4] Westkreuz station is located in a sparsely populated area on the border between the districts of Charlottenburg, Halensee, Westend and Grunewald.

The extended Stadtbahn and the curve to the southern Ringbahn crossed on the level in the system of tracks to the west of Charlottenburg station.

This was connected to the existing pair of long-distance tracks of the Stadtbahn at Heerstraße station to minimise costs.

The number of trains that could run on the Spandau Suburban Line was therefore limited by the occupancy of the long-distance tracks of the Stadtbahn.

Operation of all suburban traffic to Spandau via the Berlin–Lehrte railway, which runs further north, was ruled out because the Lehrter Bahnhof had already reached the limit of its capacity.

In addition, it was planned to remove the level junction between the Stadtbahn and the south ring curve and to construct a turnback east of Charlottenburg station.

A station would be built to improve the interchange between the two lines at the intersection of the extended Stadtbahn and the Ringbahn.

[7] During the construction, the Reichsbahn had to take into account the interests of the city of Berlin, which wanted to build an exhibition grounds on an area of around 100 hectares south of Kaiserdamm.

For this reason, the station was given a large entrance building[8] that was connected via a side road with Halenseestraße.

The entrance and exit to the station building was made from the Ringbahn platform via a pedestrian bridge.

Likewise, the station building could have been extended to the west and given a separate entrance to the Stadtbahn platforms.

[10] 16,000 to 20,000 passengers were expected to transfer traffic between the Stadtbahn and the Ringbahn on weekdays and around 700 trains stopped at the station every day.

[11] The Nazi Party plans to transform Berlin into Germania envisaged relocating long-distance traffic to the Ringbahn.

Westkreuz station was to be redeveloped with a western extension that would provide a link to the Grunewald carriage sidings.

[13] From the beginning there were problems with the subsoil, which consists of a sand-filled ice age meltwater channel.

Brademann originally planned to locate the station building above the intersection of the Stadtbahn and Ringbahn and to have a single domed train shed over the facility.

A rising skylight of the ticket hall was separated by a concrete cornice from the main structure.

At the southeast corner, the Wk signal box of the S&H 1912 type stood out from the rest of the building.

With a height of 20 metres above the tracks of the extended Stadtbahn, the building was the tallest signal box in Berlin at the time.

[8] The floor plan of the ticket hall also indicated its intended function as an exhibition ground station.

The larger north entrance would have served as an exit towards the exhibition ground, so that the streams of passengers would not have crossed.

From there, a six metre-wide iron, wood-covered bridge walkway with glass curtain walls led to the entrance to the Ringbahn platform.

During the redevelopment of the Stadtbahn and the relocation of Berlin-Charlottenburg station, this track was temporarily adapted for passenger services.
