Skistar has tremendous assets. I would be surprised if Skistars assets doesn't have the same status in the high middle class/upper class in 50 years time.
Jungfraubahn also has a tremendous assets, high moat, a long track record and low debt.
Gladstone is a asset play as well, farmland will be around and it is a scarce resource. Need to read up on it a bit more, which I need to do for everything since I just started to spend time on investing again.
I doubt the growth and scaleability in all of these, so important to get in to a low multiple, but when I get in I can sleep well for many years to come.
