Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 71, p. 217. Works number was 55277 in January 1922.
This oil-burning logging Prairie served a timber harvester based in Brookings, Ore. Founded by John E Brookings (later known for his role in creating the Brookings Institution), the town built the first railroad in Curry County in 1915-1917. The 5 was not big and its boiler was saturated, but it did have constant-lead radial valve gear and 8" (203 mm) piston valves. It was a light railroad with 60 lb/yard (30 kg/metre) rail, imposing 6%, and 30-35 degree curves.
When the C&OLC sold its assets to Westfir Lumber in 1925, the new owners renumbered the 5 as their 2.
