S17 (St. Gallen S-Bahn)
railway service of the St. Gallen S-Bahn

The S17 is a railway service of the St. Gallen S-Bahn that provides hourly service between Sargans and Rapperswil, connecting stations in the cantons of St. Gallen and Glarus. Südostbahn (SOB), a private company primarily owned by the federal government and the canton of St. Gallen, operates the service.
On its journey, the S17 passes three ghost stations: Bollingen, Weesen and Mols.
Operations
The S17 operates hourly between Sargans and Rapperswil, using the Ziegelbrücke–Sargans and Rapperswil–Ziegelbrücke railway lines. The S6 also operates between Rapperswil and Ziegelbrücke, combining with the S17 for half-hourly service, with calls at every station. Between Uznach and Rapperswil, the S17 and S6 are additionally supported by the S4 and IR Voralpen-Express, both of which do not call at intermediate stations.
The three hours long Alpstein round trip (until December 2023 offered by the former S4 circle line), is still possible by combining the S4 and S17 services.
