The Berlin U-Bahn originated in 1880 with Werner Siemens' idea to build an urban railway in Berlin. During the nine years after the German Empire was founded, the city's population grew by over one-third and traffic problems increased. In 1896, Siemens & Halske began to construct the first stretch of overhead railway. On 1 April 1897, the company began construction of an electric underground railway. The Berliner Verkehrs Aktiengesellschaft (BVG) was formed in 1928, and took over further construction and operation of the network. In 1938, the company was renamed Berlin Transport Company; the original acronym, however, remained. Since 1994, the BVG has been a public company.
