This wood-burning logging Mikado used a Radley & Hunter spark-arresting stack. Its purview covered the Enterprise, Ore timber harvester's range and included the need to take 100 short tons of trailing load up a 6% maximum grades and negotiate 25 degree curves (radii of 231 feet/70.4 metres) while rolling on standard 56 lb/yard (28 kg/metre) rail.
The 3 was later sold to the Columbia & Colitz as their 102 and went on to serve that line's successor Weyerhaeuser Timber Company.
