Data from DeGolyer Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 39, p. 318. See also the The British Columbia Archival Information Network website account at [];rad, last accessed 13 December 2012. Works number was 37125 in October 1911.
This logging Prairie duplicated the dimensions of the 2-6-2 sold to nearby Comox in the previous year and described in Locobase 13714. Most of the BCE's motive power was electric, including several also supplied by Baldwin. Still, the 940 found a role on the 65-mile (105-km) line between Vancouver and Chilliwack, meeting curves with radii as tight as 35 degrees and a ruling grade of 2 1/4%.
By 1920, BCE had sold the 940 to Carlton Logging Company of Hoquiam, Wash as their 6. CLC sold the 6 to Wynooche Timber Company, which renumbered the engine #2. Wynooche was bought out by Brady, Washington-based Schaefer Brothers Lumber in 1924, which led to a change of road number to #26.
The 26 was scrapped in 1954.
