Yes, the Sierras are one of the few locations in the world where snow is measured in feet not inches! (IIRC Norden and Truckee, CA see approximately 400 inches of snow per year!)
In the most recent issue of Trains magazine, they talk about the rotary snowplows (like a giant snow blower) and Jordan spreaders (basically heavy-duty plows on rails) that the Union Pacific uses to keep Donner Pass open in the winter.
If I'm not mistaken, Donner Pass is the requires the most effort to keep snow from closing it of any railroad pass in the western hemisphere.
