New York, Susquehanna & Western dieselized rapidly in the early 1940s, and had the distinction of being one of the first North America lines to be entirely diesel operated. The core of its fleet was a small fleet of Alco switchers and the 1,000 hp RS-1 road switchers. NYS&W had served as a coal corridor in affiliation with the Wilkes-Barre & Eastern until the late 1930s. Better known were its New York City-area suburban services between Butler, New Jersey, and Erie's Jersey City terminal on the Hudson Waterfront opposite Manhattan. Erie and Lackawanna combined their terminals in the late-1950s, and in the final years of NYS&Ws service it was terminated at Susquehanna Transfer where passengers could take a bus to Manhattan. In the mid-1960s, NYS&W petitioned to discontinue its loss-making passenger operations, which in their final days were operated by RS-1s and tired looking coaches, such as that pictured at North Hawthorne, New Jersey. North Hawthorne was an intermediate terminal, and a more frequent service operated here than on the full 38-mile run Butler. It appears that RS-1 234 is running around its train. The weed-grown yard was indicative of tough times on the historic railroad. Despite its woeful condition, NYS&W was not included in Conrail in 1976, and in 1980 it was acquired by the Delaware Otsego short line company. In the mid-1980s, it expanded its freight operations as Conrail spun-off surplus routes.
