Designated as a “DL701” by ALCo, the 1,800hp RS-36 was only slightly more successful than the RS32, with a total of 40 units produced between 1961 and 1963. Interestingly the DL701 designation was also used for the RS-11 locomotive, and this has been the cause of some confusion when tallying fleet rosters. The largest purchaser of RS36s was Delaware & Hudson with a total of 12 units. These units served the D&H well, operating in road and local freight service through the 1980s. A few units even lasted into the 1990s holding yard and local assignments, serving their original owner for nearly 30 years. Norfolk & Western eventually amassed a larger fleet than the D&H, with the acquisition of Nickel Plate’s 11 units, giving N&W a total fleet of 17 units (some with high short hoods). Other original owners included Tennessee Central, Apache, Atlantic & Danville and Chicago & North Western (single unit order).

Given their very low production numbers, it is interesting to note that a handful of RS-32 and RS-36 locomotives can still be found in service today on a few US shortlines and tourist railroads.
