Yngenio Cristobal Colon 2-4-0 Locomotives in the Dominican_Republic


Class Details by Steve Llanso of Sweat House Media

Class 5 (Locobase 14009)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 44, p 244 and Vol 54, p. 222. Works numbers were 38034 in July 1912 and 42632 in November 1915.

Similar to several other six-wheelers toiling in the sugar plantations of Santo Domingo, this design had two fewer boiler tubes and a longer stroke.
