 Lausitz proved to be not only a rich source of Spreewald gherkins but also, more importantly, of coal.In order to improve access between the neighbourhoods that emerged around Görlitzer Straße (the Wrangelkiez) and Wiener Straße (the Reichenberger Kiez), an underpass was constructed under the railway site.Opened to the public in 1910, this connected Oppelner Straße on the northern side with Liegnitzer Straße to the south.
