General Notes:

  1. OSL 3134-3138 were the only Pacific class locomotives on the Union Pacific System with 69-inch drivers; assigned to the Idaho Division
  2. The OSL P-11 4-6-2s were built lighter than other Heavy Pacifics. They were created especially for mountain service in Eastern Idaho on the Butte, Yellowstone and Teton branches out of Pocatello, Idaho Falls and Ashton. Their construction was delayed fourteen months due to War Department locomotive priorities. (Gordon McCulloch, A History Of Union Pacific Steam, 2016, page 94)
  3. Known by some as "Montana Cutdowns" due to their smaller drivers and lighter weight. (Oral history comments by Ralph Gochnour and Dave England)

General Notes:

  1. OWRR&N 3206 was retired at Huntington, Oregon, then moved to Pocatello, Idaho; donated in April 1955 to Spokane, Washington, moved by rail to Spokane, then by truck to High Bridge Park for display; deeded by donation by city to Inland Empire Railway Historical Society (changed to Inland Northwest Rail Museum) in June 1978 and moved over city streets to Interstate Fairgrounds, southeast of intersection of East Broadway Ave and North Havana Street, adjacent to former Milwaukee Road yard. Still there as of April 2009.
  2. The story is told that when the railroad offered to donate a steam locomotive to the city, representatives were sent to Pocatello, Idaho, to pick a locomotive from a group of recently retired locomotives. OWRR&N 3206 was recognized as having been seen in the Spokane area and was the locomotive selected for donation.
  3. On August 26, 2016, OWRR&N 3206 was moved, along with other pieces of equipment, from Spokane, Washington, to the museum's new site three miles west of Reardan, Washington. The movement was by rail over Union Pacific and BNSF from the Interstate Fairgrounds in Spokane, south to Cheney (20 miles), then by Eastern Washington Gateway Railroad, westward 29 miles to the museum site.
