München Moosach station

Line S1 is a line on the Munich S-Bahn network. It is operated by DB Regio Bayern. It runs from Munich Airport station and Freising to Neufahrn bei Freising station, where most trains are coupled (and uncoupled in the opposite direction). Trains continue via Feldmoching, Laim, central Munich to Munich East.

The line is operated at 20-minute intervals between Munich Airport station and East Munich. Two out of three trains an hour continue from Neufahrn bei Freising to Freising, so that the gap between trains alternates between 20 and 40 minutes.
