Lake Zürich right-bank railway line
The Lake Zürich right-bank railway line ( is a railway line in the Swiss canton of Zürich. As its name suggests, it runs down the right, or east, bank of Lake Zürich, connecting Zürich to Rapperswil. The line was opened in 1894, nineteen years after the complementary left bank railway. As built, it originally departed from the surface level of Zürich Hauptbahnhof station in a westerly direction, before performing a clockwise 270 degrees turn via a viaduct over the River Limmat and the Letten Tunnel to Stadelhofen station. Since 1990 the Letten Tunnel has  been closed and replaced by the Hirschengraben Tunnel, which takes a direct easterly route under the River Limmat from new low level platforms at Hauptbahnhof. At the same time as the Hirschengraben tunnel was constructed, the Zürichberg tunnel was constructed in order to link Stadelhofen station with the Zürich to Winterthur and Wallisellen to Rapperswil via Uster lines. As a consequence the section of the right bank line between Zürich Hbf and Stadelhofen is now part of the backbone of the Zürich S-Bahn, carrying no fewer than eight separate routes. However beyond Stadelhofen the traffic reduces to three S -Bahn routes. Routes S6 and S16 stop at all stations as far as Uetikon or Meilen respectively. Route S7 runs non-stop from Stadelhofen as far as Meilen, then serves all stations to Rapperswil. The line is long, standard gauge and electrified at supplied by overhead line. It is predominantly double-track, but with single-track sections from Stadelhofen to Tiefenbrunnen, Herrliberg-Feldmeilen to Meilen, Uetikon to Stäfa, and Uerikon to Rapperswil.
