The entire station area was opened—as Charlottenburg-Westend—in several stages from 15 November 1877,[4] but it has since been reduced to an S-Bahn platform and a pair of long-distance tracks.
The station complex was at its maximum size between its first major expansion in 1884 and the turn of the century, with four platforms and several passing tracks.
It was built in 1884 to a design by the office of the architects Heinrich Joseph Kayser [de] and Karl von Großheim.
[4] Platform A served as the terminal station for the local traffic of the Stadtbahn, which ran over the Ringbahn in the early years of the line.
Platform B served the trains of the Berlin–Lehrte railway and the Stadtbahn that continued south of Westend on the Ringbahn.
A two-track bypass was built behind it, which was necessary for electric Stadtbahn trains that were not continuing to the northern Ringbahn.
Around 1944, the traffic on the platform ended because the connecting curve from the Stadtbahn to the northern Ringbahn was closed.
The structure of the platforms and its connecting track network remained roughly unchanged until the reopening in 1993.
The construction of an additional access at the southern end of the platform towards Sophie-Charlotten-Straße[6] to be completed in 2020[7] is planned.
