Inauguration of Berlin U-Bahn Line A

On July 18, 1904, Berlin inaugurated its inaugural U-Bahn line, designated Line A, running from Stralauer Tor to Zoologischer Garten. Designed by engineer Heinrich Schwieger with Siemens technology, the electric multiple-unit trains operated on a 2.5-mile elevated and underground route. This innovation addressed severe traffic congestion in the rapidly growing metropolis amid the Wilhelmine era. The line's success spurred a subway boom, incorporating distinctive tiled stations and influencing global metro designs. It played a key role in Berlin's modernization, later expanding into today's extensive U-Bahn system and symbolizing early 20th-century engineering prowess.
