This EMU is, if I'm not mistaken, a ABDeh 8/8 Class, although the Wikipedia page seems to lack a comprehensive photo collection to go with the list of classes. For that matter, the Wikipedia article lacks even a roster.

This is one of my better shots of the train, which was an EMU like most of what the BVZ runs.

Many cog (or rack) railways in Switzerland, and for that matter the world, only use cog technology for banking, running conventionally. The BVZ Zermatt-Bahn is one such railway.
