Somewhere on the many lists I read this article drifted by.
Fitting in to this discussion is the Ingalls 4-S, built 1946. Construction of the loco was part done in AL Bham and Decatur etc and part in MS. A lot of testing done in .AL. I note that Birmingham Tank (part of Ingalls Iron Works) had a site adjacent to the Southern Railway trackage, possibly some work done there. Must be some records of testing using Southern?
The on 21 March 1946 there was a demonstration of the loco held by Southern and Southwestern Railway Club at terminal station in Atlanta. Who has more info on this demo. Anything Ingalls 4-S in fact.
