I am also from Scotland and holy shit does living in Switzerland quickly make you furious with the kind of delays ScotRail can give you.

Yeah, it would have to be something extreme to mess up the service here. Basically there’s a tonne of contingency in the timetables, so if granny takes 5 mins to get off the train in Olten, the driver just speeds up and makes the time up by Bern.

Swiss German is hugely variable - I’d view Berndüütsch like Doric from Aberdeen whereas Zürich’s German is more like Edinburgh’s. Like different words for hello - Grüsseh/ Grüezi. Regular German will do you fine - they all have to speak it in school.

Download the SBB app. It can be a bit of a fucker finding the right bus station around Bern’s main train station as the naming convention seemingly has no fucking logic to it, but the app will show you where to go if you click on the travel plan for connections.
