Originally, the S2 operated between Zurich Airport and Ziegelbrücke. With the 15 June 2014 timetable change (opening of the
Weinberg Tunnel), the route was lengthened to (without intermediate stops) and services to stations between and Ziegelbrücke were suspended. The
S27 (
March shuttle), which is not part of the Zurich S-Bahn network (or the
St. Gallen S-Bahn network), was introduced, replacing the S2 between Ziegelbrücke and Siebnen-Wangen (operates only during peak-hour). With the 15 December 2024 timetable change, the S2's southern terminus became again Ziegelbrücke, and instead
IR35 (Aare–Linth) now additionally calls at Unterterzen. == See also ==
