Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 64, pp. 277 and 78, pp. 67+. Works numbers were 54009 in November 1920 and 58755 in October 1925.
When this Oriente Province central decided its Moguls were not quite powerful enough for its maximum 2.4% grades, the sugar processor had to take account of the tight, 24 degree curves on its line. So it bought an oil-burning plantation Consolidation design from Eddystone that featured more cylinder volume and smaller drivers to generate more tractive effort. But the driving wheelbase grew by less than a foot and axle loading was still under ten tons. Four years later, the company took delivery of a duplicate.
Both were later sold to the Central San Jose, which was renamed after the 1959 Revolucion and nationalization for los Hermanos Ameijeiras. The engines were renumbered 1667 and 1373.
