Dill-Cramer-Truitt Corporation 2-6-2 "Prairie" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 14042)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 45, p. 28. See also "Suffolk's Lumber Induatry", New York Lumber Trade Journal, Volume LVII [57], whole number 676 (15 August 1914), p. 32. (Thanks to Chris Hohl for his 6 Novembef 2024 email noting the 3's fuel capacity.) Works numbers were 41229 in March 1914.

A typical Baldwin light logging Prairie built in the 19teens, the 3's specifications included specific instructions concerning ths syphon used to both suction water from a nearby water supply and eject it into a log skidder's tank. Each hose measured 25 ft (7.62 m) long. When ejecting, the syphon had to be arranged to leave at least 8" (203 mm) of water in the tender's tank. Ever conscious of the risk of exhausted cinders starting fires in the timber, the spec called for the firebox to have "the best possible arrangement to prevent sparks."

In addition to asking that the side rod oil cup capacities be increased, a "Hereafter" note explored a cab reconfiguration. "Lower throttle rod and, if possible, raise the steam valve stand dry pipe to avoid interference."

DCT was a tidewater lumber company based in Suffolk, Virginia. NYLTJ's update demonstrates the key role DCT played in the city's economy in 1914, the same year it took delivery of the 3. 25 years before (i.e.1889). lumber companies turned out 75,000 board feet of lumber per day. By 1899, that figure had increased to 100,000 board feet per day in 1904, that figure had risen to 150,000 bfpd, and in 1909 200,000 bfpd.

When DTC's new plant came on line, the article projected, it would contribute to an output of 300,00 bfpd. (The estimate included results from Montgomery Lumber Company and Crocker-Brinkley Lumber Company.) The full article describes the lumber industry in the Suffolk area in a boom time.
