the now-defunct station Olympiastadion (Olympic Stadium). The new S-Bahn system stood the test and transported 3.18 million passengers in 7,138 runs to and from the sports sites in only 17 days. The first stage was limited by the Olympic Games in 1972. Because of the enormous time pressure, not all lines could be equipped for a 10 or 20 minute cycle. The second stage was necessary mainly because of the increasing traffic volume. In 1973 and 1974, the Deutsche Bundesbahn established the following construction measures: Own S-Bahn tracks were to be built on the railway tracks from Lochhausen to Nannhofen (now Mammendorf) and from Munich to East Grafing, So as not to hinder long-distance and regional transport on the respective routes. As new settlements developed in Esting, in the south Neuperlachs and in Unterschleißheim new settlements, the new breakpoints Unterschleißheim in the year 1977, Neuperlach Süd in 1977 and Esting in 1980. In addition, The railway line to Herrsching was to be extended two-way between Freiham and Weßling. Since then the Munich S-Bahn network has been expanded multiple times. On 28 May 1980, it was extended to Mammendorf. On 3 November 1979, it was extended to Ebersberg (S4). S5 was extended to Herrsching in 1984. In 1992, the route between Ismaning and the newly opened Airport Munich II was put into service as S8, followed by S1 extension on 29 November 1998. Further Development With the timetable change on 12 December 2004, the ten-minute headway on the S 4 from Maisach to Zorneding and on the S 5 from Germering-Unterpfaffenhofen to Deisenhofen was introduced during rush hour, doubling the number of trains offered from three to six per hour. Since 11 December 2005 this is also offered on the western section of the S 2 to Dachau. This means there are now 30 trains per hour and direction on the trunk line during rush hour. In August 1998, the federal government, the Free State of Bavaria and Deutsche Bahn decided on a 266-million-euro package to introduce this ten-minute headway on several lines. The main point was the modernization of the control and safety technology between Pasing and Ostbahnhof, including the installation of Linienzugbeeinflussung. Between 2001 and 2005, construction work on the external lines continued as part of this program. In addition, new S-Bahn stations were opened on 10 June 2001 in Starnberg Nord (S6 West) and on 11 December 2005
