The first five were constructed in 1943 and 1944 using the boilers from their unsuccessful K-5 class three-cylinder 2-8-2 locomotives that had been built by the American Locomotive Company's Schenectady works in 1925.

Two additional locomotives were converted in 1946 and 1947 using a pair of K-4 class 2-8-2s as donors at the Decatur Shops in Illinois .

The engines were semi-streamlined with long "elephant ear" smoke deflectors, and painted blue with a broad white stripe trimmed in red down the side of the locomotive and on the steam dome; the tenders received a similar paint job. The locomotives’ number was painted on the tender, and in later years the flag logo was applied to the deflectors. They ran until 1956.[1]
