UP 900077 (as UP 077) was designed and built by Barber-Greene Company of Aurora, Illinois, which produced asphalt paving machines for highway construction. The company also produced specialized trenchers and loaders for construction materials.

As early as the mid 1920s, Barber-Greene produced snow loaders for highways and roads, used by street departments to remove snow from city streets, transferring the snow by single conveyor belt to waiting dump trucks. The single belt design was changed to two-belt design and adapted as a snow loader for the railroads, including Union Pacific and New Haven. Three similar machines were also furnished to the New Haven (NY,NH&H) railroad, which kept three 2-8-2 steam locomotives in service solely for snow loader/melter service, until the all of the machines were retired in 1958.

General Notes:

  1. UP 900077 and 900078 were assigned to North Platte until their retirement in 1968.
  2. (Photo of UP 077 / 078)
  3. UP 900077 and 900078 were used to clear yard tracks by using a mechanical loading mechanism which lifted the snow and placed it on to a conveyer belt, which then loaded the snow into a tender-like tank car (no. 900078) where the snow was melted to reduce its volume; the melter was equipped with steam coils that used steam piped from a steam locomotive.


  1. UP 900077 was built in October 1949 by Barber-Greene Company of Aurora, Illinois as UP 077; renumbered to UP 900077 in 1959; retired in May 1968

The following comes from Jack Wheelihan, posted to Trainorders.com on December 1, 2015:

When I was in North Platte, Neb during late 1963, getting ready to put the EMD GP35/DD35 Demonstrator set together, I remember seeing the Challenger in the roundhouse. They had shop steam piped into it, and when I inquired as to what the purpose of the steam pipe with all the holes in, attached to the bottom of the pilot was for, the Foreman explained "the plan". It was supposed to be for snow removal at all the turnouts throughout the yard. However, the downside was, unless the MoW "operator" was VERY careful with the steam supply to that pipe under the pilot, not only was the snow removed, but also all the ballast, tieplates, and some spikes! We did get some snow while I was still there, but didn't get to see the Challenger "in action".

The folks at the North Platte Roundhouse told me that it did indeed move under its own power, when I was there in late 1963. They had shop steam piped into it so that it would be ready at a moments notice, i.e. boiler with nice hot water and steam pressure, so that lighting the oil fire took only a few minutes. She would then be quickly ready for "work" by the time a crew showed up, as the roundhouse forces/Hostler had her ready to go, quickly.

UP Jull-type Snow Plows

Builder Date
UP 03004 UP 065 Southwark Jul 1889 Jull 1 Mar 1949 sold for scrap
  UP 066 Rogers Feb 1890 Jull 2
(Rogers 4256)
(1899) to Union Pacific, Denver & Gulf; to C&S 0200 in 1899

General Notes:

  1. UP 065 and 066 had wooden construction and steel underframes
  2. These two snow plows were first and second of eleven "Jull Centrifugal Snow Excavator" snow plows built.
  3. The Jull plows had a large spiral screw placed diagonally across the front of the plow to clear the snow. The design did not work as well in deep or heavy snow as the Leslie design.
