The line connects the Chur–Rorschach line at the St. Margrethen border station in the Swiss canton of St. Gallen with the Lauterach Nord junction in Lauterach in the Austrian state of Vorarlberg, where it joins the Vorarlberg line.

History

The Vorarlberg Railway (Aktiengesellschaft k. k. priv. Vorarlberger Bahn) opened the cross-border line between Austria-Hungary and Switzerland on 23 November 1872. The first through express train between Zürich and Munich ran just under a year later, on 1 November 1873. The line, as with most of the Austrian railway network, was nationalized prior to World War I. The line was electrified on 2 January 1949.

Between 2010 and 2013, the Alpine Rhine bridge was replaced by a new one and the adjacent Lustenau Markt station was suspended. Between 2016 and 2021, Lustenau station was modernized. In 2021, the section between Lustenau and Lauterach was renewed, including the reconstruction of Hard-Fussach station and upgrade of the section between this station and Lauterach West to two tracks. The new station Lauterach Unterfeld (replacing the former Lauterach West station) was introduced. Additional measures taken included improved noise protection for residents and flood protection.

Route

The line diverges from the Chur–Rorschach line at St. Margrethen and runs eastward over the single-tracked bridge across Alpine Rhine (which forms the Austria–Switzerland border) and across the tracks of the International Rhine Regulation Railway to Lustenau. East of the bridge, the line now turns north. Between Lustenau station and Hard-Fussach station, it follows the artificial Rhine canal in northward direction, before turning towards east again as a double tracked railway. East of Lauterach Unterfeld station, it connects to the Vorarlberg railway line in both northward and southward direction via two connectors.
