business in 1984, nothing changed at first. It was not until 1989 that the Senate of Berlin began to rebuild the Ringbahn. It noted that there was a particularly large need to renovate Westkreuz station. In 1993, the entrance building and signal box had to be demolished; the signal box had a dangerous overhang of 30 cm. The station was equipped with escalators and lifts. The first section of the Ringbahn was put back into operation on 17 December 1993. As a result the Westkreuz was restored as an interchange station after 13 years. Westkreuz was also the terminus of the regional railway services toward Spandau between 27 June 1994 and 31 May 1997. This required a temporary timber platform to be built on the freight tracks of the Ringbahn, which was then demolished as part of the renovation of the Ringbahn freight tracks. As part of the renovation of the Stadtbahn in Westkreuz, both the tracks and the two Stadtbahn platforms have been completely renovated since 2004. The work was completed in time for the 2006 FIFA World Cup. The station is one of 20 so-called Stammbahnhöfen (stem stations) of the Berlin S-Bahn with local supervision of trains (ZAT-FM). At the Ringbahn platform, the train is dispatched by the driver using the driver's cab monitor. Contrary to the standard ZAT dispatching procedure, special services on the track towards Spandau are dispatched by local supervisors. The building of an additional eastern entrance has been approved by the State of Berlin. In 2016, this was expected to be completed in 2018. It has not been built (as of November 2020). Structure The station was built to a plan of Richard Brademann. The only access to the station is via the street of Am Westkreuz. Until 1993, the entrance building was at the end of the section controlled by Electro-mechanical signalbox Wk. A pedestrian bridge spans the freight tracks of the Ringbahn and the Westend–Halensee passenger track, connecting the station building to the Ringbahn platform. Stairs connect the Ringbahn platform to the two Stadtbahn platforms. Former entrance building and signal box The construction of the entrance building took about a year and a half. Its large size was due to the intended function as an exhibition station. The other traffic was expected to be predominantly interchange traffic and a small amount of local traffic, according to Brademann, so the installation of a
