Zürich Seebach railway station
Trains on the S6 provide a half-hourly connection to Zürich Hauptbahnhof station, taking 12 minutes for the journey via the southern connector and Oerlikon station. In the opposite direction, S6 trains continue to Baden station, taking 28 minutes for the journey. The station also sees significant through freight traffic, most of which takes the Furttal line in order to avoid passing through central Zürich, using the northern connector onto or off the Zürich–Winterthur line.
S25 (ZVV)
Trains run hourly, covering the distance from Zürich Hauptbahnhof to Ziegelbrücke in 43 minutes, to Glarus in 60 minutes, and to Linthal in 94 minutes. Despite being classified as an S-Bahn train, the S25 actually covers the distance between Zürich Hauptbahnhof and Ziegelbrücke in a shorter time than the parallel RegioExpress service to Chur. This mirrors the performance of its predecessor, the Glarner Sprinter named train, which was itself classified as a RegioExpress service.
