When Frederic C. Dumaine became President of the D&H in 1967, one of his high priorities was to upgrade the remaining passenger service. The PA1's were refurbished and repainted in a Santa Fe-like paint scheme, and used with ex-Rio Grande Budd stainless steel passenger cars on the daily New York-Albany "Laurentian" and "Montreal Limited" trains. In addition to the four AT&SF PA1's, the D&H also acquired an ex-New Haven PA (#0783) for spare parts. For a while, the locomotives were well cared for, but came to an end when D&H was taken over (by court order, along with the E-L) by the N&W at the inception of the Penn-Central merger. When Amtrak took over most rail passenger service, the D&H trains were not included, and the PA's were out of work. Two (17 & 19) were traded to GE. However, Hurricane Agnes in the summer of 1972 destroyed much of the neighbor Erie-Lackawanna, rendering the court order null and void. New management was brought in, and the new D&H President, C. Bruce Sterzing, re-acquired the two PA's from GE. The 244 prime movers powering the PA's were worn out, but the D&H managed to get three of them operable, and convinced the State of New York to use the D&H equipment on a partial state-sponsored restoration of the New York-Montreal train service in cooperation with Amtrak. The D&H was in need of reliable passenger locomotives, and in a joint project with Morrison-Knudsen, the Model 244 prime movers were removed from 16 and 19, and the bodies were shipped to Boise, Idaho in June 1974 for installation of Model 251F prime movers. The returnig locomotives were classed as PA4's, a model never produced by Alco. After returning to the D&H, its attended assignment was taken over by Amtrak's Turboliners, and it was sold to a dealer (along with the other three PA4's), who sold them to FNM in Mexico. It was wrecked, and stored, later purchased by Dolye McCormack, to be cosmetically restored for display at the Smithsonian.
