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 in Untermenzing (S2 West). Some already existing stations on the outer routes could also be made wheelchair-accessible in the financial framework of the project. On 21 November 2005, the section of the airport line S 8 within Unterföhring was moved underground, this was at the request of the town. On 13 December 2009, a new stop "Hirschgarten" was inaugurated on the S-Bahn trunk line between Laim and Donnersbergerbrücke. On 14 September 2013 a new Freiham stop was opened on line S8 close to the one that had been closed decades before, which is to connect the new residential area Freiham. It is located one kilometer east of the 1975 decommissioned station Freiham. Construction had begun on 12 June 2012.
