In 1942, American Locomotive Company began delivery of 20 class J-3 4-8-4s to the Nashville, Chattanooga & St. Louis. Southern pride prevented these bullet-nosed 4-8-4s from being called "Northern" types on this railroad, which styled them the "Dixie" type. Their 70-inch drivers were suitable for the NC&StL's mountainous territory, and they had 250 p.s.i. of boiler pressure and cylinder dimensions of 25x30 inches. Weighing 400,500 pounds without tender, they exerted 57,000 pounds of tractive effort. Some were fitted with running board skirting in yellow paint, and were known as the "yellow jackets." No. 570, first of the "yellow jackets," is shown here when newly delivered from ALCo. The photo was made available to our Random Steam Collection courtesy of Charles B.
