Operations

The S2 operates every hour between Nesslau-Neu St. Johann (Toggenburg) and Altstätten SG (St. Galler Rheintal), using the Bodensee–Toggenburg line between Nesslau-Neu St. Johann and St. Gallen, the Rorschach–St. Gallen line to Rorschach, and the Chur–Rorschach line to Altstätten SG. Save for the branch from Wattwil to Nesslau-Neu St. Johann, the S2 is paired with the S4 to provide half-hourly service.

History

Until the December 2018 timetable change, the S2's westbound terminus was St. Gallen. Service from St. Gallen to Nesslau-Neu St. Johann had been provided by the S8. Scheduling issues with the S8 prompted a swap, with the S2 taking over the S8's former schedule west of St. Gallen.
