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 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 before the ordered brake test and load runs, the vehicle stands under steam in front of the Pontresina depot. G.P., who carried out the overhaul, stands next to the spinning wheel. On the side, the flaps in front of the wheel drive are open. The spinning wheel with a diameter of 250 centimeter (8,2 ft) rotates at up to 170 revolutions per minute.
