The Chicago Burlington & Quincy converted a 45-foot flatcar to Wedge Snow Plow no. 205065 in 1929. The railroad used it for many years on the line between Sterling, Colorado, and Cheyenne, Wyoming. The Burlington Northern, successor to the Chicago Burlington & Quincy, donated it to the museum in 1972 [GPL].
