First Section of Berlin U-Bahn Opens

On June 28, 1900, Berlin inaugurated its initial U-Bahn segment, a 2.5 km elevated and underground route using electric multiple units. Designed by Siemens & Halske, it alleviated street congestion in the growing metropolis. Key figures included Werner von Siemens. The line featured innovative third-rail power and stations like Potsdamer Platz. This marked Germany's entry into rapid urban transit, influencing subway designs worldwide. Lasting impact included expansion into today's extensive network, supporting Berlin's industrial and cultural boom.
