The S2 was activated on 12 December 2004, and operated initially between Mariano Comense and Milano Porta Vittoria.With the change of timetable on 15 June 2008, the line was extended from Milano Porta Vittoria to Milano Rogoredo, where there is interchange with regional trains and long-distance services to and from Genoa, Bologna and Mantua.
