With its establishment of the Intercity network on 26 September 1971, Ingolstadt Hauptbahnhof became part of the IC network. Nevertheless, long-distance services in the winter timetable 1971/72 were still quite limited in Ingolstadt, since initially, only one Intercity train pair operated to Ingolstadt, the IC 123 ("Nymphenburg") and the IC 126 ("Herrenhausen"). In the following years, however, IC services at Ingolstadt station increased. So in the winter 1991/92 timetable, there were services between Ingolstadt and Munich and between Ingolstadt and Frankfurt and the Ruhr every two hours.
