Service historyEdit
The S2 was created along with the S1 and S3 on 9 January 1984, when the Berliner Verkehrsbetriebe (BVG) took over the S-Bahn network from the East German Deutsche Reichsbahn in West Berlin: the S2 initially ran between Lichtenrade and Anhalter Bahnhof, before being extended northwards to Gesundbrunnen on 1 May 1984, and Frohnau on 1 October 1984.<ref name="db-20210609">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
In 1990, the S1 replaced the S2 between Gesundbrunnen and Frohnau.<ref name="sbmap-1990">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
