Atlanta & West Point 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 32 (Locobase 12011)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 17, p. 174. Works numbers were 12355-12356, 12358 in December 1891.

This set of Eight-wheelers served the West Point Route for more than 20 years each. 34 retired first in 1912, 32 followed in 1916, and 33 was sold in 1923 to locomotive rebuilder/ reseller Georgia Car & Locomotive. GC & L apparently didn't find another railroad to buy the engine, so it scrapped in October of that year.
