Yes, we Swiss are attracted by any narrow gauge (having been in Chama just 7 weeks ago...). Remember Soni Honegger -also a Swiss :-)
By the way, I got my narrow gauge bug on the railroad below. It's related to the Rio Grande beacuase it runs along a river called "grand eau", that is "big water" or "big river", which is Rio Grande :-) The official name was "Aigle-Sepey-Diablerets" (Eagle - Sepey - little devils). It sill exists today:
