What if the next winter comes? Since the beginning of the railway era, it has been necessary to clear the tracks during snowfall or drifting snow. The range of railway service vehicles includes everything from simple snow plows to large snow plows and high-performance snow blowers. At the Deutsche Bundesbahn, it became necessary in the 1960s to replace the old steam-powered snow blowers. Various heavy-duty rail vehicles equipped with Beilhack diesel snow blower units were tested in the Alps, in the Allgäu region, and abroad. A disadvantage of these vehicles was the need for an additional locomotive to push them. To make snow clearing even more efficient, a self-propelled high-performance snow blower was developed. This could handle snow depths of up to 3 meters, ensuring preparedness for any weather whims. However, after extensive test runs, the series delivery to the Deutsche Bundesbahn was delayed until the early 1990s.
