Inauguration of Berlin's First U-Bahn Line

On June 8, 1903, Berlin's first U-Bahn line from Stralauer Tor to Potsdamer Platz began operations, representing a leap in European urban rail infrastructure. Designed by Siemens & Halske with electric multiple units, the 2.5 km route alleviated street congestion in the growing capital. Key figures included engineer Heinrich Schwieger. This innovation influenced subway designs worldwide and supported Berlin's industrial expansion. The line's success led to rapid network growth, surviving wars and division to become a cornerstone of modern public transport in the reunified city.
