Operations

S1 service on the Lake Line between Triboltingen and Ermatingen, Lake Constance

The S1 operates every half-hour between Schaffhausen and Wil over the Lake line (Schaffhausen–Romanshorn), Bodensee–Toggenburg line (Romanshorn–St. Gallen), and St. Gallen–Winterthur line (St. Gallen–Wil). It shares the Konstanz–St. Gallen and St. Gallen–Wil portions with various regional and long-distance trains, plus the S5 between St. Gallen and Gossau SG.^[5] Between Wil and Uzwil it passes Schwarzenbach and Algetshausen-Henau stations, which are both disused since 2013.

The S1 allows for combined round trips by train and boat on the section along the High Rhine and Lower Lake Constance (Schaffhausen–Kreuzlingen), which is operated by the URh navigation company. In addition, Romanshorn and Kreuzlingen Hafen stations are both located close to landing stages on Upper Lake Constance, which are served by boats and ferries.

History

Until the December 2013 timetable change, the S1 continued east from St. Gallen to Altstätten SG, on the Chur–Rorschach line. The service was truncated when the Rheintal-Express [de] was extended west from St. Gallen to Wil.^[6] With the December 2018 change the S1 began running half-hourly and InterRegio 13 replaced the Rheintal-Express.^[7]

Between the December 2018 and December 2021 timetable changes the S1 operated every half-hour between Wil and St. Gallen, continuing from St. Gallen to Schaffhausen as the S8.^[5] With the December 2021 timetable change, the entire Wil–St. Gallen–Schaffhausen route was designated as the S1, albeit with the timetable color formerly associated with the S8.^[8]
