Data from DeGolyer, Vol 63, pp. 289+ Works number was 52342 in September 1919.
Lawrence Turnure & Co. was the New York City agent that arranged the purchase of this superheated oil-burning plantation Mogul. Six inch (152 mm) piston valves admitted this potent steam to the cylinders.
Instructions for shipment give an insight into some of the special considerations such export orders called for: "Locomotive to be shipped all set up on frames, with the excepton of cab, boiler, etc. providing that none of the packages weigh more than 20,000 lb [9,072 kg]. Purchaser has facilities for handling pieces of 20,000 pounds (gross) and wish to do as little re-erecting as possible."
The Cristobal Colon was one of the oldest sugar centrals in the DR. In 1921, it passed into the control of Felipe A Vicini, then head of the Nariño family.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 54, p. 236. Works number was 43587 in June 1916.
Porcella, Vicini & Company bought outside-frame plantation Moguls in several sizes and fuel for its DR estates. Like the others, the Trieste (named for a city in the family's native Italy) sported an improved Radley & Hunter spark-arresting stack. Perhaps to gain more adhesion, this specification called for 2 more short tons on the drivers than the others.
