‘Westkreuz’ means ‘west cross’: here the Stadtbahn and the Ringbahn cross.
The station opened on 10 December 1928 as an interchange between the two lines. Because it was also meant to serve the planned exhibition grounds, it was named Ausstellung (‘exhibition’). On 15 January 1932 it was renamed Westkreuz. Together with Ostkreuz, it is one of the two interchanges between the Stadtbahn and the Ringbahn.
