Not yet, but as the old saying goes: "You never know." just as I write this some one in Pan Am rail's HQ will OK a scheme with the PanAm logos and colors*. It would be an improvement on the current dark gray with orange stripe scheme they use now. I suspect that they will put PanAm "Globes" on the locomotives where the stylized Gs are now when the urge strikes them. Don't hold your breath for this to happen. But as I said, you never know!
