S7 (Munich)


Line S7 is a line on the Munich S-Bahn network. It is operated by DB Regio Bayern. It runs from Wolfratshausen via Höllriegelskreuth, central Munich, Höhenkirchen-Siegertsbrunn and Aying to Kreuzstraße. Trains reverse in Munich East station and, in order for S-Bahn services from St.-Martin-Straße to be inserted into the S-Bahn line while simultaneously reversing to run into the S-Bahn tunnel under central Munich or vice versa, the line between Munich East station and the flying junction between München-Giesing and Fasangarten stations is one of the few in Germany that has traffic running on the left.
The line is operated at 20-minute intervals between Höllriegelskreuth and Höhenkirchen-Siegertsbrunn. Two out of three trains an hour continue from Höllriegelskreuth to Wolfratshausen and from Höhenkirchen-Siegertsbrunn to Aying, so that the gap between trains alternates between 20 and 40 minutes. Only one train an hour continues from Aying to Kreuzstraße. It is operated using class 423 four-car electrical multiple units, usually as two coupled sets. In the evenings and on Sundays they generally run as single sets.
The line runs over lines built at various times:
S-Bahn services commenced on 28 May 1972 as S-Bahn line 10 between Wolfratshausen and service from Wolfratshausen to Holzkirchen wing station of Munich Hauptbahnhof as they could not yet continue through the S-Bahn trunk line tunnel because the so-called southern lines tunnel, which passes under the long-distance tracks towards Pasing and the S-Bahn trunk line, was not yet available. With the opening of the southern lines tunnel on the S-Bahn route on 31 May 1981, the S-Bahn line from Wolfratshausen continued on the S-Bahn trunk line; as a result it was renamed as line . Line took over the section of from Munich East to Kreuzstraße.
