During the revision of the BDeh 3/6 25, the vintage BDeh 2/4 # 24 (lettered as ABDeh 2/4) from 1967 is running the hourly service on the standard gauge cogwheel Rorschach-Heiden-Bergbahn (part of the Appenzeller Bahnen since 2006). The train from Rorschach, down in the fog on the shore of Lake Constance, is entering Heiden station in the sun.
