Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 64, p. 71. Works numbers were 53276 in June 1920 and 56035 in January 1921.
These oil-burning plantation tanks served a small sugar Central located in Sancti Spiritu Province. The railway used 56 lb/yard (28 kg/metre) rail and offered only 0.5-1% grades. Minimum curve radii were a tight 51.8 metres (170 feet). The little truck under the fire box swung a full 5" (127 mm) to each side.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 64, p. 76, Vol 72, p 13, and Vol 78, p. 38. Works numbers were 57094 in September 1923, 58003 in September 1924, 58240 in February 1925 and 58331 in March.
Still constrained by the small volume of sugar production and the tight alignments of this Sancti Spiritu central, the Natividad bought a third radial tank that had slightly larger dimensions than the two oil-burners shown in Locobase 14833, but burned wood. The change in fuel prompted a change to the Rushton Improved cabbage stack. The combination apparently suited because the company went back to Eddystone for a duplicate a year later and bought two more within six months of that purchase.
