Also operational, a few times a year, is an original steam-powered rotary snowplow, an essential device in the line's commercial service days. (The rotaries were retired in 1964, along with the remaining steam engines that pushed them, and snow clearing was done by caterpillar tractor.) While it is not needed as the tourist season is only in the summer months, it is a spectacle in operation, and the White Pass runs the steam plow for railfan groups once or twice a winter, pushed by two diesel locomotives (in 2000 only, it was pushed by two steam locomotives, Nos. 73 and 40).
