Data from Baldwin Locomotive Works Specification for Engines, 1903, as digitized by the DeGolyer Library of Southern Methodist University Vol 28, p. 218 and Vol 54, pp. 97+. Works numbers 31664-31665 in September 1907, 32084-32085 in October, 36691 in November 1911, 38016 in December 1912, and 41674 in September 1914.
Stewart Sugar was formed in 1906 as a reorganization of the Silveira Sugar Company. The factory they completed was located near Ciego de Avila in the Province of Camaguey. Obviously, the company settled quickly on this Mogul design. The specification called for each locomotive to pull 20 25-ton cars up a 1/2% grade. The 1911 order contained the note: "Hereafter: Throttle lever to be lengthened 6" for convenience of engineer." The May 1912 specification notes that the locomotive was "to negotiate curves of 439 ft [134 metres] radius [13 degrees] slowly." Sharpest curves on main line had a relatively gentle radius of 938 ft (286 m) or a little more than 6-degree curvature.
