Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 65, p. 129. See also the FGS history at [] . Works numbers were 54859 in June 1921.
Many logging companies and short line operators adopted this relatively small Prairie for all kinds of service. FGS was formed in 1907 to break the "box shook" cartel (box shook was the very thin wood used for crates) by managing the combine of fruit growers and smll independent mills in Northern California.
The railway that supported this business opened in 1913. Its track mileage would grow to 50 miles (80.5 km) and included maximum grades of 4.5% on 50 and 56 lb (25 and 28 kg/metre) rail. The oil-burning 33 was the only engine that was bought new; it operated at the Lassen Lumber Mill at Susanville, Calif.
The FGS closed its railway in 1953.
