The S12 and S11 are regional railway lines of the S-Bahn Zürich on the Zürcher Verkehrsverbund (ZVV), Zürich transportation network. The S12 is one of the network's lines connecting the cantons of Zürich and Aargau, whilst the S11 connects the cantons of Zurich, Schaffhausen, Thurgau and St. Gallen .

Line S12 commences at Brugg station, in the canton of Aargau, and follows the Olten to Zürich line as far as Zürich Hardbrücke station and the approaches to Zürich Hauptbahnhof station. Passing through the lower level platforms at this station, the line then passes through the Hirschengraben and Zürichberg tunnels, and Stettbach station, before joining the Zürich to Winterthur line.

The S12 follows this line as far as Winterthur Hauptbahnhof station, running non-stop between Stettbach and Winterthur. At Winterthur, alternate trains take different routes, running either over the Tösstalbahn as far as Winterthur Seen station, or over the Winterthur to Etzwilen line as far as Seuzach station.

In the outbound direction, the S11 commences at Zürich Hardbrücke station and follows the same route as the S12 to Winterthur Hauptbahnhof station, from where it continues to either Schaffhausen, Romanshorn or Wil. In the inbound direction, the line commences in Schaffhausen or Winterthur and terminates at Altstetten, one stop after Hardbrücke.
