This probably looks like a snow blower, but the railroads call it a snow plow. A rotary snow plow, yes, but still a snow plow. A 184 ton, 52 foot long snow plow. Caveman 92223 explains:
The Union Pacific Railroad designed and built this monster in the Omaha Shop. This rotary snowplow is the heaviest snowplow ever built.
This baby boasts a GM/EMD 16-cylinder, 3,000 horsepower, turbocharged diesel engine that drives an electric generator which provides the power to turn those massive 12-foot rotary blades at 150 RPM.
