For the first time in several decades, the R 12 steam snow blower was faced this day with solid snow compacted throughout the winter. The Xrot d # 9212 or "R.12" had been built in 1913 for the main network of the Rhaetian Railway. Unlike the snow blowers of the former Bernina Railway, it is not self-propelled, but has a small steam engine that can drive an axle for maneuvering. After being officially discarded in 1968, it was transferred to the Blonay-Chamby museum railroad in 1971, where it underwent some visual refurbishment. In 1996, there was an exchange of the "Rotary" Xrot d # 9214 (ex Berninabahn), which was at the steam railroad Furka Bergstrecke, with the Xrot d # 9212 of the Blonay-Chamby. It was put in the depot in Gletsch. In 2002, on the initiative of Martin Horath, she was transported to Arth Goldau and started with the careful and extensive complete refurbishment, which was finally successfully completed in 2020. The snow blowing composition with cogwheel steamlocomotive HG 4/4 # 704 is on the adhesion section in the gorge of the Furkareuss behind Realp, running towards the Wiler bridge.
