Santa Ana 2-8-0 Locomotives in El_Salvador

Class Details by Steve Llanso of Sweat House Media

Class Ateos (Locobase 11626)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 15, p. 94. Works numbers were 10035 in June 1889 and 11902 in May 1891.

This was a good-sized Consolidation for the 3-ft gauge, especially given the year in which it was produced.. Both locomotives -- Ateos and Colon -- were first operated by the Acajutla & Sonsonate before that railways was nationalized.
