Inauguration of the Berlin U-Bahn

Berlin's U-Bahn debuted on August 16, 1904, with the initial 2.5 km stretch serving six stations. Built by Siemens & Halske using cut-and-cover methods, it featured innovative multiple-unit electric trains that eliminated the need for locomotives. This network transformed urban mobility in the growing capital, supporting industrialization and setting standards for subway design adopted in cities worldwide.
