Berlin Hochbahn Extension Opens

On June 21, 1904, the Berlin Elevated Railway (Hochbahn) opened an important extension serving the growing metropolis. This electrified line enhanced connectivity between residential areas and industrial zones, using innovative steel viaducts to navigate dense urban environments. Key figures included engineers from Siemens and the city administration. The project reflected Berlin's rapid modernization and addressed overcrowding on existing trams. It set standards for elevated rapid transit systems worldwide and laid groundwork for today's U-Bahn network, significantly shaping the city's economic and social fabric.
