Data from [] and DeGolyer, Volume 80, pp. 280+.Works number was 60256 in November 1927.
This Prairie Mallet for logging service was considerably more powerful than the two earlier 2-6-6-2Ts delivered to Bloedel-Donovan Lumber Mills in 1924 (Locobase 4044). The specs said that this oil-burner would encounter 2% adverse grades when pulling loads, 3 1/2% when hauling empties, all on 70 lb/yard (35 kg/metre) rail and around 24-degree curves (240 feet/73 metre radii). And at the time of its manufacture, 14's railroad included more than 90 miles (145 km) of line.
This later engine's tender was lettered for Bloedel Donovan Lumber Mills before its delivery. (Larson Lumber had merged with BD in 1913.) The engine then went to Port Angeles Western (in Port Angeles, Wash) and then Rayonier, Inc. of Sekiu, Wash.
The 14 was withdrawn in 1964 and scrapped in 1968.
