Nicaragua Government 2-2-2 Locomotives in Nicaragua

Class Details by Steve Llanso of Sweat House Media

Class Nindiri (Locobase 20689)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 14, p. 75. See also "Steam Inspection Car", Railroad Gazette, Volume 21 (24 May 1889), p. 335.Works number was 8981 in December 1887.

Baldwin's specification page for this little inspection car contains detailed instructions about just how to finish the inspection saloon located ahead of the engine compartment. It measured 7' (2.13 m) wide and 8' 3" (2.51 m) long. Fitted with a sofa manufactured by J G Brill across the rear and five rattan chairs supplied by Baldwin, the car could also hold extra folding chairs that stored under the sofa. Flooring could be either parquetry or wood carpeting "of tasteful design." Heavy plate glass for windows and front windscreens. The carbody was made of bay mahogany.

All three axles were equalized. The front truck traversed through a swing bolster, the rear was fixed.

The Nicaraguan government sold its railway to the privately held FerroCarril del Pacifico, which renumbered the Nindiri as 11. Sometime before 1926, the 11 was withdrawn.
