Although the 12 was satisfactory (Locobase 14486), the Santa Fe's next two Consolidations squeezed more heating surface out of the boiler to cater to an increased cylinder volume supplied by 8" (203 mm) piston valves. The sugar processor switched to oil fuel as well. The 4, which was the second to bear that number, was identical, but weighed 77,500 lb (31,153 kg) on the drivers and 85,000 lb (38,555 kg) on all five axles.Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 54, p. 265. Works number was 45600 in May 1917.
Apparently pleased with the difference superheating a boiler made to its performance (see Campina, #11, in Locobase 14485), the Santa Fe returned a year later to order another plantation Consolidation. The 12 was scaled up in size, but retained the same proportions as the 11 except for a slight increase in cylinder volume and the adoption of 8"(203 mm) piston valves. Like the other 2-8-0s ordered by the Bartram Brothers for DR plantations, this engine burned hard coal.Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 54, p. 263. Works numbers 43566 in June 1916 and 53960 in November 1920.
As the benefits of superheating steam from a locomotive boiler became accepted facts in the US, more and more types of engines began appearing with such installations. Although small and seemingly destined for slow duty, the Campina was a plantation Consolidation that mirrored the earlier saturated-boiler Guasa (Locobase 14483), but had a remarkably well-tailored superheater layout. As with the Guasa, Baldwin's notes stress that the coal was hard and the water was bad. Unlike many such "conversions", the 11's design used smaller-diameter tubes than its saturated cousin and relatively few superheater flues. Nevertheless, combined heating surface actually increased 11% over that of the Guasa. Eventually the 11 was sold to South Porto Rico Sugar and was still in service 30 years after its original delivery. The 14, which came on the road more than four years after the 11, inevitably weighed more, putting 62,700 lb (28,440 kg) on the drivers and 69,850 lb (31,683 kg) on all five axles. It was later sold to the Guanica Centrale. Sometime later, the GC sold the engine to the Central Barhona as their #6.Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 54, p. 259.

One of the several sugar mills in the DR owned by the West India Sugar Finance Corporation, the Santa Fe was located in San Pedro de Macoris and was established by Augusto Russell in 1880. The Bartram Brothers bought this plantation Consolidation for the Santa Fe, a service that the Baldwin specs cautioned would mean the water was hard (so "give special attention to boiler work") and the coal was hard.. Like many Baldwin 2-8-0s for this duty, the Guasa had an outside frame and a Radley & Hunter cabbage stack, the latter of an improved pattern. The Bartrams followed with a very similar engine that was superheated; see Locobase 14485.
