First Section of Berlin U-Bahn Opens

The opening of Berlin's initial U-Bahn segment revolutionized urban mobility in the growing metropolis. Designed by Siemens & Halske, the 2.5-mile elevated and underground line used electric multiple units and featured innovative stations with island platforms. It alleviated street congestion from horse-drawn trams and connected key districts including the Tiergarten. Key figures included industrialist Werner von Siemens, whose company supplied the technology. The success spurred rapid network expansion and influenced subway designs across Europe. Its lasting impact includes serving as the backbone of Berlin's public transport system through world wars and reunification.
