The self-propelled 0-6-0+0-6-0 steam snow blower Xrot d # 9213 of the Rhaetian Railway, built in 1910 by SLM Winterthur as R #1051 for the then independent Bernina Railway, has been preserved as a historic vehicle. Until 2020, demonstration trips with the impressive machine were carried out in winter in the area of the Bernina Pass at around 2250 meters above sea level. Then a comprehensive overhaul was due. A single employee of the Rhaetian Railway refurbished the Xrot d # 9213 at the Pontresina depot and it is now complete. On the day of the ordered brake test and load runs, the vehicle is standing in front of the shed in Pontresina with opened side flaps, which shows the drive for the spinning wheel. The vehicle has 6 cylinder in total, two each for the threeaxle bogies and two for the spinning wheel with a diameter of 250 centimeter (8,2 ft). The spin wheel rotates at up to 170 revolutions per minute.
