Data from Angus Sinclair, Railway and Locomotive Engineering, May 1902, p. 202; and DeGolyer, Volume 24, p. 224 and Volume 30, p. 199. Works numbers were 20221 in March 1902 and 30374 in March 1907.
Prairie locomotives fitted with tenders didn't usually act as freight haulers. This engine was an exception as it served the Mayari District iron mines located on Cuba's north coast and owned by Bethlehem Steel. Baldwin sold mostly all-adhesion switchers to this mining company (see Locobase 20918 for the five 0-6-0s) but occasionally persuaded them to adds some truck.
These two engines were essentially identical, but five years apart in arriving. A note in the latter specs addressed a balance issue: "Move back eq[ualizer] beam fulcrum so as to take weight off rear tr[uc]k & transfer it to rear drivers, making w[eigh]t on rear truck 10,790 lb [4,894 kg] [and] making back driver spr[in]gs proportionately stronger."
