Operations

The S4 operates hourly in both a clockwise and counter-clockwise direction. A full journey around the circle takes approximately three hours. In Uznach, which lies to the west of the junction between the Uznach–Wattwil and Rapperswil–Ziegelbrücke lines, the trains reverse their direction of travel. The S4 service is operated by Stadler Rail Flirt/Flirt-3 EMUs of Südostbahn (SOB).

History

Prior to the December 2013 timetable change, the S4 operated between St. Gallen and Uznach. Local service between Uznach and Sargans was handled by an hourly regional service that ran between Ziegelbrücke and Chur.[4] Service southeast of St. Gallen toward Sargans was handled by various local services, but only the Rheintal-Express [de] operated over the whole route.[5]
