The highlight of my October 2012 trip was finding the Zentralbahn's ancient class 110s were still active. More than that, they were being used to work the premier trains over the Meiringen - Interlaken section.
110.021 was photographed east of Brienzwiler working IR2218, the 09:55 Luzern - Interlaken Ost Golden Pass service, on 6 October 2012.
