Nazareth 2-8-2 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class Almirante Muniz (Locobase 13978)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 44, p.155. Works numbers were 40114 in July 1913.

The EF de Nazareth, as the Nazareth Tramway was then named, ordered both a Consolidation and a Mikado in 1913. This was the bigger of the two, more than double the size of the 2-8-0.
