Denver & Rio Grande Western Steam Locomotive No. 318 (N)

This C&S rotary snowplow operated over a number of Colorado mountain lines from 1899 until 1965. Large spinning blades on the front threw snow high and far to either side of the track, clearing the way for trains. Power to spin the rotary blades was generated by a steam engine located in the plow. The plow cannot move itself and must be pushed by locomotives.
