St. Gallen–Winterthur railway line

The SGAE applied for a concession for the easily-built route south of Uzwil’s local hill, the Vogelsberg, from Schwarzenbach via the Bettenauer Weiher and Oberuzwil to Flawil.

Starting in 1903, the SBB duplicated the line in stages and electrified it in 1927 at 15,000 Volt 16 ⅔ Hz.

At the same time, the Algetshausen-Henau halt was opened and the Bühler industrial railway in Uzwil was handed over to the company.

The Winterthur Hegi halt was opened in December 2006 as part of the expansion of the Zürich S-Bahn.

In long-distance national traffic, the line is part of the West-East axis between St. Gallen and Geneva operated by InterCity (IC) trains.

In regional traffic, the line is used by InterRegio (IR) trains between Chur and Wil via St. Gallen (replacing the former Rheintal-Express, REX).
