At trainfest, I found (and purchased) a Bachmann Daylight painted in Chessie Steam Special. (Still working on pictures of it) In looking it up, I heard mention online of a Daylight in Amtrak, I'm intrigued. Mostly, because I just did an old Lionel up in AMTK Phase 5 with no prior awareness that Bchmann beat me to it.
I don't know about the model, but a Amtrak 4449 is aucrate. On her way back from being part of the 76 freedom train, Amtrak sponsered the trip, as such the locomotive stayed in Freedom Train colors, but had Amtrak painted in small black letters on the side of the tender.
