Line 11 between Auzelg and Sihlquai/main station will be replaced by construction line 50. From Bahnhofstrasse/main station, it will now run to Tiefenbrunnen station via Paradeplatz and Bellevue.

| Auzelg – Oerlikon station – Bucheggplatz – Schaffhauserplatz – Stampfenbachplatz – Sihlquai/main station (from there, line 50 will continue to Frankental) | Bahnhofstrasse/main station – Paradeplatz – Bellevue – Tiefenbrunnen station |
After the timetable change in December 2026, line 11 will run as usual to Auzelg. It will serve the Auzelg – Oerlikon station – Bucheggplatz – Stampfenbachplatz – Bahnhofquai/main station – Bahnhofstrasse/main station – Paradeplatz – Bellevue – Tiefenbrunnen station route.


The Bahnhofquai/HB stop is being extensively renovated and converted to make it barrier-free. It will therefore be closed for one year from 14 December 2025.
