Me and my husband are going to travel to Interlaken from Paris from 05.07.2025 to 12.07.2025. We have return flight from Basel Euroairport to CDG, Paris, at 10.10 am. So, for that I am booking super saver pass for the early morning train route in which shows that
Interrupted service: Tecknau - Olten
Duration:
12.07.2025 - 14.07.2025
Interrupted train service between Tecknau and Olten.
This is due to construction work.
The restriction lasts from 12.07.2025, 02:00 until 14.07.2025, 04:30.
You have to expect changed timetables.
Passengers travelling between Sissach and Olten please use the replacement bus service (EV).
Bikes cannot be transported.
Please consult the online timetable for your service.
The online timetable will be updated.
So should I not book this train route, or can risk the timing? Since my flight is in early morning, so I was planning to reach by 8.15 am max to have enough time. Will this above mentioned EV will also be there in my route. How can I take this?

Thanks a lot in advance for your time and help.
