Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 54 p. 43. See also Cesar J Ayala, American sugar kingdom: the plantation economy of the Spanish Caribbean 1898-1934 (University of North Carolina Press, 1999). Works number was 43659 in July 1916.
A larger locomotive among the standard line of Baldwin double-ended saddle tank plantation locomotives. Note the extra axle under the rear tank and bunker to carry a bigger fuel supply.
