Simpson Logging


Class Details by Steve Llanso of Sweat House Media

Class Koo-Ley-Ku-I-Tan/8/C-9d (Locobase 12481)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 23, p. 235. See also Fred Jukes, Philip Van Wyck and Bruce B. Cheever, "The Bellingham Bay & British Colombia Railroad Company", The Railway and Locomotive Historical Society Bulletin No. 84 (October, 1951), pp. 7-24 (30 pages), p.22; and builder's photo at Trainweb entry [], last accessed 21 September 2026. Works numbers 18718 in March 1901.

Logging in Mason and Grays Harbor counties on Washington's Olympic Peninsula imposed some severe demands on locomotives and these are reflected in Baldwin's specifications for this wood-burning Consolidation. Curves of up to 20-deg radius, grades of 7% (yes, 370 feet to the mile/104 metres/km). That latter incline was to be scaled by this locomotive pulling one loaded car of 30 tons on the log track at 20 mph (32 kph). Or it could push logs between the rails, for which the specs required Baldwin to "provide means for wetting slide log way, between tracks." The tender was sized to allow 2,100 gallons for the boiler - enough for a 12-mile (19.3 km) round trip.

Several source report that while Simpson Logging ordered the locomotive on 20 November 1900, it entered service as a Phoenix Logging engine in 1901. Baldwin's builder's photo reproduced in the Trainweb entry shows the 18" Radley & Hunter inversely tapered stack containing spark-arresting netting.

Locobase hasn't been able to establish the meaning of the locomotive's name. Two sources offer different definitions such as "race horse" (Chinook language) or "fish". According to the BB&BC history cited above, Simpson sold the engine to locomotive reseller Hicks Locomotive & Car Works and Hicks sold it to the BB&BC. As engine 8, she was converted to coal burning and proved to be "very powerful" wrote the authors of the R&LHS study,"...for years the principal freight engine, pulling the daily log train.".

When the Chicago, Milwaukee, St Paul & Pacific Railroad acquired the BB&BC in 1920, they placed it in its own C-9c class and renumbered it 7564. In July 1926, the Milwaukee Road sold the 7564 to Hines Lumber of Seneca, Ore
