[2][3] The Wabash Railroad's class P-1 comprised seven 4-6-4 steam locomotives rebuilt from 5 Class K-5 2-8-2's numbered 2600-2604 and 2 Class K-4 2-8-2's numbered 2743 and 2744 .

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]

Models

Scale models exist of the P-1s, most notably in O gauge by MTH and Lionel. An HO (1:87) version was available in brass from Hallmark Models.
