Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 41, p. 3. Works number was 38055 in July 1912.
The Cotton Belt website -- [], accessed 29 May 2007 -- says the D&SW "...originated at Caruthersville, Missouri (on the Mississippi, and extended almost due west to Deering, where it veered southwest to Hornersville and connected with the Cotton Belt." The section from the lumber mill at Deering to Hickory was completed in 1903, the remainder took the next eight years.
The D&SW was owned by Wisconsin Lumber, which only goes to show that corporate names derived from geographic references cannot be relied upon. In the specs, the D&SW is shown to have rails weighing between 35 and 55 lb/yard (17.5-27.5 kg/metre), but a relatively gentle 10 degrees for the tightest curve radius. Still, each truck was given the leeway to swing 4 inches (102 mm) to either side of center.
