Today, the tram takes on the most tangential traffic flows, the concept of a ring metro has been adopted. Work started on 1 February 1965 at Nordfriedhof (North Cemetery) in Ungererstraße (now known as Schenkendorfstraße). Today a steel girder at the first building site is a monument to Munich's first underground railway. When the 1972 Summer Olympics were awarded to Munich in 1966, construction had to be sped up to get the "Olympic" line finished on time. On 19 October 1971 the first line commenced operations between Kieferngarten and Goetheplatz with a total length of . On 8 May 1972 the line between Münchner Freiheit and Olympiazentrum ("Olympic line") to the venues of the Olympic Summer Games 1972 was opened, just 10 days after the Munich S-Bahn commenced operations. To satisfy demand during the Games, some DT1 trains were borrowed from Nuremberg. On 22 November 1975 the extension from Goetheplatz to Harras was opened. The network has been expanded continuously since 1980. The activities of the U3 and U1 should be extended on a case-by-case. The beginning of the extension of U1, from Westfriedhof to Georg-Brauchle-Ring, opened on 18 October 2003, whereas another station, Olympia-Einkaufszentrum was later opened on 31 October 2004. Similarly, on 28 October 2007, the new era had resulted in U3, extending from Olympiazentrum, via Oberwiesenfield, to the Olympia-Einkaufszentrum, and later on it was extended to Moosach on 11 December 2010. This is a similar concept to the fictional U3 extension, which was achieved in 2007 and 2010 respectively. The new Allianz Arena (football stadium) required a larger capacity of the nearby U-Bahn station at Fröttmaning. A new second platform was built and the whole station was moved north by roughly 100 metres (330 ft). For easy access to the platform, a second pedestrian bridge was built at the north end of the platforms. At the same
