- Bülach –) Hardbrücke – Zürich HB – Effretikon – Wetzikon
Extended from Hardbrücke to Bülach during rush hour, operating non-stop from Glattbrugg. (
The core of the service links Wetzikon, in the east of the canton of Zürich, and Zürich Hardbrücke, in central Zürich. This core service runs via the Hinwil–Effretikon line, joining the Winterthur–Zürich line at Effretikon. It then runs via the Zürichberg Tunnel and stopping at Zürich Stadelhofen and Zurich Hauptbahnhof. During peak hours service continues north via the Oerlikon–Bülach railway to Bülach.
The following stations are served:
Up until December 2018, the S3 operated via the Zürich–Baden railway as far as Dietikon, instead of turning north to Bülach. Alternate trains continued further along the Zürich to Olten line, from Dietikon to Aarau, in the canton of Aargau. An extended S11 replaced the S3 between Hardbrücke and Aarau.
Over the core route between Wetzikon and Hardbrücke, the normal frequency is one train every 30 minutes. A limited number of trains operate to and from Bülach during peak hours. A journey over the full length of the service takes 60 minutes.
