A rotary snowplow is a piece of railroad snow clearing equipment that has a sizable circle of rotating blades on its front end that clear snow from the track in front of it. The wedge snowplow served as the precursor to the rotary snowplow.
The conventional automated technique for removing snow from train lines was to use wedge snowplows. These forced snow away from the tracks and off to the side. This method cannot easily clear deeper drifts since there is simply too much snow to move. The rotary snowplow was created for this reason.
When the snow is too deep or hard-packed for conventional plows, rotary plows are frequently used. In mountainous areas where a high speed accident may be fatal, the ability to move slowly is often advantageous because there is no need for train momentum to break up the snow.
A locomotive or more locomotives must be linked behind a rotary plow because many of them are not self-propelled. The huge circular assembly at the front of the plow is rotated by an engine inside the carbody of the plow. This wheel’s blades slash through the snow, forcing it to flow into a channel directly behind the disk and out of an output chute above the blade assembly.
