Ingeniero Perseverancia / Ingenio Perseverancia / Ingenio Porvenir 2-6-0 Locomotives in the Dominican_Republic


Class Details by Steve Llanso of Sweat House Media

Class Anita (Locobase 12457)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 23, p. 162. Works number was 18415 in December 1900.


Class El Soco (Locobase 13846)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 39, p. 203 and 49, p. 67. Works numbers were 37065 in October 1911 and 40802 in November 1913.

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.


Class Hugh Kelly (Locobase 14772)

Data from Baldwin Locomotive Works, Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 63, pp. 261. Works number was 47232 in December 1917.

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.


Class Maria Victoria (Locobase 12570)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 24, p. 113. Works number was 19790 in November 1901.

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.
