Atlanta & West Point / Western Railway of Alabama 4-4-0 "American" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 16 (Locobase 16657)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 17, p. 174. (Thanks to Chris Hohl for his 24 November 2023 email correcting coal and water capacities and convincing me that the 16 belonged to the WRA -- this new entry is the result.) Works number was 13063 in November 1891.

In addition to the three Eight-wheelers sent to the Atlanta & West Point in 1891 (see Locobase 12011), Baldwin produced one more for the sister road WRA. Its specifications matched those of the A&WP engines. All four used a relatively long adhesion wheelbase for 4-4-0s rolling on 66" drivers.

The WRA later sold the 16 to the Alabama, Tennessee & Niorthern. Sometime later the AT&N changed its road number to 91. Roster notes for the latter show that it was still in service in May 1935.


Class 32 (Locobase 12011)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 17, p. 174. (Thanks to Chris Hohl for his 24 November 2023 email correcting the coal and water capacities and the railroad that operated the fourth locomotive of the batch.) 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. Like the single locomotive of the same design on the Western Railway of Alabama (Locobase 16657), these used a relatively long adhesion wheelbase for 4-4-0s rolling on 66" drivers.

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.
