From a nice hike from Brienz (1857 ft) up to the Brienzer Rothorn (7362 ft). The Brienzer Rothorn cog railway is operated by steam locomotives. Most of the steam locomotives were built after 1970. See http://en.wikipedia.org/wiki/Brienz_Rothorn_Bahn

This panorama shows the top station of the cable car going down to Sörenberg and the Brienzer Rothorn in the back.
