Among the holdings of the Pacific States Lumber Company of Tacoma, Wash was the Cascade Timber Company of North Yakima. It was founded in 1902 and operated independently until 1957, when it merged with Boise-Payette to form Boise-Cascade.
A coal-burning saddle-tank logging Prairie locomotive was in the minority of such engines in the Pacific Northwest-most were oil-burners. But otherwise the superheated 107 fell right into line on moderate curves of 16 to 20 degrees and up short grades of 3% and a half-mile (0.8 km) grade of 2 1/2%. The hotter steam meant 8" (203 mm) piston valves.
The 107 operated for Cascade Timber until it was sold $16,865 in 1942 to Ventura County Railway in Oxnard, Calif as their #2. 21 years later, the 2 wsa sold to W E Standish of Port Hueneme, Calif in February 1964. Sold again in 1970 to Terry Durkin for his Orange Empire Trolley (later Railway) Museum, where it went on display in November 1973, then into tourist railroad service. The 2 was extensively overhauled from 2001-2006, then placed back in operation.
By the time of its latter-day 1,472 day inspection in 2021, the #2's tender capacity included 5,000 US gallons (18,925 litres) of water and 800 gallons (3,028 litres) of oil fuel. (See Chris Guenzler's description of the 1,472 SDI that all operating steam locomotives must undergo.)
