The prototype RSD-4 arrives in 1951 from Alco.  Original RSD-4 owners included:  Central Railroad of New Jersey, Chicago & North Western, Kennecott Copper, Santa Fe, and Utah Railway.  Alco constructed 36 examples between 1951 and 1953.
 
The more popular RSD-5 debuts in 1952 with 204 examples built by 1956 and production end.  Original owners for RSD-5 diesels included:  Birmingham Southern, Central Railroad of New Jersey, Chesapeake & Ohio, Chicago & North Western, Ferrocarril del Pacifico, Milkwaukee Road, NdeM, Pennsylvania Railroad, Santa Fe, Southern Pacific (SP, SSW, T&NO), and Utah Railway.
