Union Pacific 2-8-0 Steam Locomotive 529 is a 2-8-0 steam locomotive built by Baldwin Locomotive Works in 1903 as builder's number 21672. Weighing 197,300 pounds and burning oil for fuel, it is typical of the hundreds of 2-8-0 locomotives that worked on the Union Pacific Railroad. Baldwin built the engine in 1903 as no. 969 for the Union Pacific subsidiary Oregon Short Line. Later renumbered Union Pacific (Oregon Short Line) 529, it spent most of its working life in Idaho. In December 1948, Edward Hines Lumber Co. bought the locomotive for use on its 10-mile spur from Westfir to Seneca, Oregon, where it connected with the Hines-owned subsidiary Oregon & Northwestern Railroad. Hines retired the locomotive in 1965 and donated it to the Northwest Railway Museum. The Oregon & Northwestern Railroad ran between Seneca and Burns, Oregon, and was completed by the Edward Hines Lumber Company to log the Bear Valley timber sale in Oregon's Malheur National Forest. The original Bear Valley timber sale in the 1920s required construction of a sawmill, a 30-mile railroad extension from Crane to Burns, and a 50-mile common-carrier railroad from Burns north to Seneca. The Bear Valley tract covered 67,400 acres of public timber and was described as possibly the largest volume of timber ever sold in the Pacific Northwest. Edward Hines began as a clerk for the lumber wholesaler S.K. Martin Company in the Chicago, Illinois, area and started his own lumber company in 1892. As logging slowed in the Midwest and South, the Bear Valley timber sale provided an opportunity for the company to expand into the Northwest.
