EVF de Itabapoana 2-6-0 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 15161)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 66, p. 319. Works number was 53698 in September 1920.

Norton Megaw bought this little wood-burning freight Mogul, which was fitted with the spark-arresting Rushton Improved cabbage stack. Very similar to some 2-6-0s produced for Dominican sugar companies and their 30" gauge, the 4 had a wider track, but shorter tubes. Its railway was located in the State of Espiritu Santo, which is on the Atlantic coast just north of Rio de Janeiro.
