Salvador 4-6-0 Locomotives in El_Salvador


Class Details by Steve Llanso of Sweat House Media

Class 12 (Locobase 13768)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 36, p. 254. Works numbers were 35472-35473 in November 1911.

These mixed-traffic Ten-wheelers were suitable for both freight and passenger operations and contributed the basis for the Consolidation that would be bought for the same railroad fifteen years later (Locobase 15364).
