S23 Langenthal–Olten.
S23 services between Langenthal and Olten will now be available on the weekend, in addition to the weekday services as before. This means that the Langenthal–Olten service can be provided daily at half hour intervals from 7am to 8pm.
Olten–Aarau–Arth-Goldau.
There will be two pairs of trains running on Saturday and Sunday: between Olten–Aarau–Arth-Goldau in the morning and from Arth-Goldau to Aarau in the evening. The trains will run according to this schedule:
- Departing Olten at 06:37 and 08:37 for arrival in Arth-Goldau at 07:41 and 09:41 respectively.
- Departing Arth-Goldau at 17:23 and 19:23 for arrival in Aarau at 18:15 and 20:15 respectively.
RegioExpress Olten–Wettingen.
All Olten–Wettingen REs will once again stop in Wildegg.
S26 Olten–Schönenwerd.
The S26 service from Olten–Schönenwerd will provide a connection to Zürich HB via the RegioExpress at Aarau (rather than Lenzburg as previously). The arrival and departure times for RegioExpress and InterRegio trains will change.
Evening trains Olten–Biel/Bienne.
Evening trains after 10pm between Olten and Biel/Bienne will now operate daily instead of only at the weekends.
- 22:53 from Biel/Bienne to Solothurn
- 23:11 from Olten to Solothurn–Biel/Bienne
- 23:16 from Solothurn to Olten
Aargau S-Bahn.
- The S-Bahn in Aargau will provide more services and better connections. The S29 will now operate between Turgi–Aarau–Zofingen at half hour intervals from 5.30am to 10.30pm.
- The S11 between Aarau–Zürich HB–Winterthur–Seuzach/Wila will now always stop in Othmarsingen. The additional S11 trains for peak hours will also operate daily instead of only on weekdays.
- The S42 will stop only in Mägenwil (instead of Othmarsingen) since Othmarsingen has been permanently added as a stop on the S11 route in the direction of Zürich HB–Muri AG. In the direction of Muri–Zürich HB, the stops will remain the same as for the 2019 timetable: S42 trains will stop in Othmarsingen not in Mägenwil.
Stability measures for Bern and Zurich.
Certain critical connections between regional and long-distance services will no longer be offered in order to improve the timetable stability and punctuality in Bern and Zurich.
S23 stop in Dulliken.
Dulliken will initially only be served by S23 services at the weekend. This is due to construction work at Mägenwil station and subsequent construction work planned at Lenzburg station. Train speed must be limited for safety reasons. The extra travel time required for this means that the Dulliken stop cannot always be served. Buses between Dulliken and Däniken will operate as a replacement service, which will provide a connection to and from S23 services in Däniken.
