Quisqueya Sugar Co 2-6-0 Locomotives in the Dominican_Republic
Class Details by Steve Llanso of Sweat House Media
Class Cuba (Locobase 6748)
Data from [
] . See also Frank Moya Pons, History of the Caribbean: plantations, trade, and war in the Atlantic world ( ). Additional data from DeGolyer, Vol 63, pp. 293+. Works numbers were 52848 in January 1920 and 54271 in January 1921.
The first of the pair of Moguls was given the odd name of Cuba (for an Estate in the DR). This little plantation engine design did not lack for power and its valve train included 6" (152 mm) piston valves.
A second engine named Camache put 40,000 lb (18,144 kg) on the drivers and 46,000 lb (20,865 kg) on all four axles. It trailed a tender weighing 19,000 lb (8,618 kg) empty and 41,000 lb (18,597 kg) loaded with half again as much water (1,800 US gallons/6,813 litres) but 1/2 ton less coal (3 1/2 tons/3.2 metric tons).
By the late 1920s, 92 percent of all sugar grown in the Dominican Republic came from American-controlled companies including the CQ.
