A rotary snowplow is a type of railway snow removal equipment designed to clear large amounts of snow from the tracks. It has a large, rotating blade at the front that spins at high speed to break up the snow and throw it off the track. The snow is then pushed to the sides, allowing trains to pass safely. Rotary snowplows are especially useful in areas with heavy snowfall, where traditional plows may not be effective. They are often used in the most extreme weather conditions to keep railways clear and prevent disruptions to train services.
