Alabama & Vicksburg 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class D (Locobase 6081)

Data from the 1926 Alabama & Vicksburg locomotive diagram book supplied in March 2004 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 28, p. 148; Works numbers were 27011, 27055 in December 1905; 29328, 29346 in October 1906; 30003-30004, 30022 in January 1907; 30075 in May; 32099-32100 in October; and 35954-35955 in January 1911.

This is the Alabama & Vicksburg freight Ten-wheeler class equivalent to the Vicksburg, Shreveport & Pacific's D1s and the New Orleans & North Eastern A-3. The spec sheet for the 450-451 specified a change in the whistle: "Omit chime whistle and use whistle of coarser sound" than on earlier engines.

Only 5 of this group were superheated; the D1 entry (Locobase 6080) shows the result.

The rest were saturated-steam at least until 1926. Three -- 443, 445-446 -- were sold to the Louisiana & NorthWestern in March 1922 as 29-31. Illinois Central took 6 of the others, 3 of which went to the Yazoo & Mississippi Valley.
