Berlin elevated railway extension opens

On June 15, 1904, Berlin's elevated railway system added a significant new section that enhanced connectivity across the growing metropolis. The extension used steel viaducts and electric multiple-unit trains, reflecting the latest in German engineering. It alleviated street congestion and supported the city's rapid industrialization and population growth. Key figures included engineers from Siemens and city planners who integrated the line with existing steam railroads. The project influenced later U-Bahn and S-Bahn developments and remains part of Berlin's iconic public transit heritage.
