#900081
Union Pacific
— 1966 —
Designed and built by the Union Pacific Railroad in the Omaha Shop, this rotary snowplow is the heaviest ever built weighing 367,400 lbs. Its cutting wheel could throw snow far to either side of the track as it was pushed forward at four to six mph. It is not self propelled and must be pushed by 3 or 4 locomotives. Number 900081 is powered by a GM/EMD 16 cylinder, 2,000 hp turbocharged diesel engine that drives an electric generator which provides power to turn the 12' rotary blades at up to 150 rpm. A steam generator heats the cab, prevents the fuel and water pipes from freezing and can thaw out the cutting wheel if it gets struck. The plow engineer controls both the plow and the trailing locomotives. This snowplow is 52'2" long, 17' high, and was last used in Green River, WY, in the mid-1980's. The circular windows in the front of the plow revolve to keep them clear of snow.
Donated in 1994 by the Union Pacific Railroad
