Alabama & Vicksburg 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 408 (Locobase 12480)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 23, p.232. Works numbers were 18719-18720 in March 1901 and 19362-19363 in August.

The 4 Moguls in this entry were essentially identical to the dozen supplied to its stablemate, the Vickburg, Shreveport & Pacific, in 1898 and described in Locobase 6079.

After careers of between 15 and 25 years on the A & V, all four entered second careers for other users. 437 was sold first to the Sumter & Choctaw in 1916 as their 101. 439 went to the locomotive rebuilder/reseller Birmingham Rail & Locomotive in 1917, which later sold it to Cuban company Mora & Zayas. Also located in Cuba was the Central Limones, to which the 438 was sold in 1926. 440 wound up working for Birmingham, Alabama's Newcastle Coal Company.
