History
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 Unterterzen and services to stations between Siebnen-Wangen and Ziegelbrücke were suspended.[6] The S27 (March shuttle), which is not part of the Zürich 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).
