From Wikipedia, the free encyclopedia:
“Pankstraße is a Berlin U-Bahn station located on the U8. It was opened on October 5, 1977 (Rümmler) with the line’s extension from Gesundbrunnen to Osloer Straße. The station’s name derives from its location: It sits under the intersection of Pankstraße and Badstraße.
The actual spelling of the station’s name is under debate. The German orthographic rules call for the spelling “Pankstraße”, but the signs inside the station spell “Pankstrasse”.
Like the station Siemensdamm (Berlin U-Bahn), the station is constructed as a “Multi Purpose Facility”. It is prepared and partially stocked to be used as a NBC shelter. It is specified to sustain 3339 people for 14 days.”
