Inside the cab of the steam rotary snow blower Xrot d # 9213, built by SLM Winterthur in 1910 for the then independent Bernina Railway as R # 1051. The image, taken with a focal length of 16 mm, is a bit deceptive, but in reality it is very narrow in this driver's cab, which controls both the movement of the snow blower and the rotation of the wheel. The red pointer pointing to the left on the red R shows that the snow is hurled to the right. With the crank handle on the far left the ejection direction of the snow can be changed. Above is a signboard indicating the maximum speed of 36 km/h and the maximum boiler pressure of 13 atü (184,9 Psi). In the middle, there are two throttle levers. The red one is for the blast wheel, the other for running.
