Last Thursday afternoon, I was driving in Nashville TN and just happen to look down from an overpass and saw a A-A lashup of F's (in midtrain) moving towards downtown in the Gray paint with White and Black lightning bolt graphics. (I'm no authority on diesels, they might have been E's) I really doubt they are in revenue service - are they being ferried somewhere?

Actually, you saw two NYC E-8s, moving to new ownership in Medina, NY. They were owned by Mike Fox (who also owns the NYC RS-3 in Kansas), and are original NYC units, not fakes.
