Strictly from the NYC side of the merger, it appears the vast majority of the Central's F-3 A's were traded to EMD in 1964-65 (for GP-35s?), some a few years earlier (for GP-20/30s?).
#s 1617, 1619, 1635, and 1875 (originally dual service F-3 #3501) made it to the PC but were retired before the end of 1968.
#1633 made it to the PC but I don't have its disposition.
No B units survived past 1965.
This is out of 34 F-3 A (30 freight units, 4 dual service) and 18 B units (16 freight, 2 dual service) the NYC rostered.
The source of this info is Edson's "NYCS Diesel Locomotives".
I'm 99% sure that no NYC A-units (including F-7As) were renumbered during the PC era, and those that made it to CR also held onto their NYC #s. I think some (if not all) F7 Bs were renumbered.
Hopefully someone else can fill in the Pennsy side of the equation.
