Which routes in Lausanne had that? I never noticed any dual use buses when I lived there. It isn’t surprising, Seattle used to have dual engine buses in the 80s/90s that were diesel until they went into the downtown bus tunnel. They got rid of that when they brought the train in, and I guess the buses were cleaner by then as well.

I lived there up to about eight years ago, and I recall most of the routes running through the center city were dual. I couldn't name route numbers at this remove, though.
