Steam Sausage Train

For those wanting more info.

Thank you. That's where I was looking. I'm not finding reviews about it and wondered if it's a 'worth it' thing to try or if we're better spending our time exploring other options in the area.

Here's trip advisor reviews, which seem pretty positive- https://www.tripadvisor.co.uk/Attraction_Review-g1130556-d2270746-Reviews-Brienz_Rothorn_Bahn-Brienz_Bernese_Oberland_Canton_of_Bern.html

I’ve never heard it called that way. It is an interesting trip though. And if you are interested in steam in general you can combine it with a trip on the Blüemlisalp lake steamer.

Note that these are modern steam engines. They were build in the 90ies. If you want really old trains go up the Schynigge Platte. The locomotives there are over a century old…

Suggestions for other unusual ways to make memories?

It depends on what kinds of things your family likes, but these two come to mind:
