In August 2018, Youngstown Steel Heritage announced their intention to purchase 3639 and move it to their museum, with the goal of restoring it to operating condition, and eventually back to its original number and paint scheme. In September 2018, the group announced that they had successfully purchased the locomotive. However, the status of the project is unknown as the related pages have since been taken down. The locomotive continues to be stored offsite at the VMT.

The rear truck, called the HT-BB, for High Traction B+B arrangement, was tested successfully but advances in traction motors obviated the need for four-axle trucks. This testing was not related to the development of the HTCR three-axle radial truck first seen under EMD SD60s and SD60MACs and made standard on the early

A "Passenger Start" switch was installed inside the cab electrical cabinet; in the "COMM" position the units were held in Parallel, in the "FRT/PASS" position normal transition was made. They stayed on the commute route (often working in freight service on weekends) until 1985 when

ordered 14 SDP45s in 1969 and 1970. Intended only for freight service, these units had standard (angled) long hood ends, and the extra space aft of the radiators had concrete ballast where a passenger unit would have a steam generator and venting. Their longer frames permitted a larger fuel tank
