Key changes to the 2019 timetable for the Mittelland region.
Due to construction work in Oensingen, the IC 5 between Solothurn and Olten will be diverted and will not stop at Oensingen between 1 April and 25 October 2019. During the construction phase, from Monday to Friday during times of peak traffic additional shuttle trains will operate between Oensingen and Olten (without stopping).
Bern–Olten–Zurich main station
The IR 17 Bern–Burgdorf–Olten–Zurich main station will now stop at Zurich Altstetten in both directions. This means that the departure and arrival times at Zurich main station will change by one to two minutes (departing from Zurich main station at xx.53, arriving at Zurich main station at xx.06). In the night from Sunday into Monday, the IC 8 to Zurich main station (departing at 00.02) will only go to Zollikofen. On Monday, the first two IR trains from Zollikofen will run to Zurich Airport and Zurich main station (departing at 04.13 and 04.43). The connections between Bern and Zollikofen will be guaranteed by a rail replacement service.
Ten RE Biel/Bienne–Delle (F) train pairs going to Meroux (Belfort-Montbéliard TGV) will be extended daily, some of which will have a connection to the TGV lines. SNCF trains will also operate between Belfort, Meroux and Delle. With the RE trains stopping at Courfaivre and Courtételle, these stations will receive a half-hourly service alternating with the S3.
Olten–Zurich main station
RE Olten–Aarau–Wettingen: travelling from Olten–Wettingen, three trains will not stop at Wildegg (Aarau departing at 07.48, 16.48 and 17.48). This will affect two trains (Aarau arriving at 07.11, 08.11) travelling from Wettingen–Aarau. The RE Wettingen–Olten service will always arrive at Brugg AG at xx.59 (instead of xx.00).
The S26 will arrive at Rotkreuz on the hour and will now travel to Olten (instead of Aarau). Olten offers connections to the IC trains to Bern and Lucerne.
The additional trains will now only operate as the S23 between Langenthal and Olten during times of peak traffic. Two additional trains will also run between Olten (departing at 15.16) and Langenthal (departing at 15.21).
The S29 will only operate between Aarau and Turgi (instead of Langenthal–Olten–Aarau–Turgi as before). It will now run a half-hourly service at weekends too and will be expanded by two hours every evening. (now up until 10 p.m.).
In times of peak traffic, the S11 will be condensed to a half-hourly service between Aargau und Dietikon. These trains will not call at Othmarsingen.
