This sugar plantation was based in San Pedro de Macoris (later famous for cranking out an surprising number of major-league baseball players). The specs for the latter engine, named Jagual, note that the line presented maximum gradients of 2 1/2%, relatively gentle curves of 13 degrees (442 foot/134.7 metre radii), and rails weighing 25 and 35 lb/yard (12.5 kg and 17.5 kg/metre). Tweaks to the earlier design included the substitution of a heavy steam hose for the El Soco's steam pipe in the coupling of the steam brake system between engine and tender. A note reports that the pipe frequently broke on sharp curves.

The two earlier Baldwin Moguls delivered to this Hugh Kelly-owned sugar central were bigger than this oil-burning plantation engine; see Locobase 13846. Named for the baron that owned several Ingenios, the 7 had to tackle the 4% grades, and curves with radii of 441 feet (134.4 m) on 25-35 lb/yard (12.5-17.5 kg/metre) rail.

At the same time Cuba's Santa Gertrudis Plantation Railway took delivery of a Mogul (Locobase 12301), this identical design was built for this Dominican sugar grower.
