Operations

The S12 operates every 30 minutes between Sargans and Chur, using the southern end of the Chur–Rorschach line. In Sargans, an hourly connection is made with the S4, which operates in a circular fashion west over the Ziegelbrücke–Sargans line and north up the Chur–Rorschach line. The S12 is supplemented by various long-distance trains.[3]

History

Prior to the December 2013 timetable change, the S12 designation was used for services on the narrow-gauge St. Gallen–Trogen line of Appenzell Railways. That service was renamed S21, while S12 was applied to services running between Sargans and Chur.[4][5]
