Sumpter Valley Railway 2-8-2 #19 at the Portland Union Station Centennial

Sumpter Valley Railway #19 is the first of a pair of narrow-gauge 2-8-2 Mikados built for the eastern Oregon railroad by the American Locomotive Company in 1920. #19 & #20 were replaced on the Sumpter Valley in 1940 by a pair of used Baldwin articulated 2-6-6-2 Mallets. The tenders from the Mikados were put behind the Mallets, and the Mikados were sold to Alaska's White Pass & Yukon, where they served until 1957. The Mallets were sold to a railroad in Guatemala in 1947, and the tenders went with them. The Sumpter Valley reacquired the two Mikados in the 1970s and got the tenders back from Guatemala.

#19 was restored at the Brooklyn Roundhouse in Portland, Oregon, in the early 1990s. It had recently been completed and was brought to Union Station's 100th Anniversary on May 11, 1996, before being returned to the Sumpter Valley. A section of track at Union Station was converted to the narrow 3-foot gauge to allow #19 to be fired up and operate back and forth.
