This is the largest and heaviest rotary snowplow built. It is 56'2" long, 17' high and weighs 376,400 pounds. (That's the same as 62 African Elephants!) Its 12' diameter cutting wheel could throw snow far to either side of the track as it was pushed forward at four to six mph. Its hydraulically operated wings can open to permit a 14' wide cutting swath of snow. The cutting wheel can revolve up to 150 rpm. It is not self propelled and must be pushed by up to four locomotives.
