Snowfighters At the base of Union Pacific’s Donner Pass crossing, one of Southern Pacific rotary snowplow sets rests at Truckee, California, on March 12, 2004. Sitting next to the plow are two spreaders with SP MW No. 430 facing east. Both are essential pieces of snowfighting equipment used for keeping Donner Pass open each winter, each providing a unique type of snow removal that is dependent on snow depth and conditions.
