Check out this new fangled critter I found when I got to work today
Blue card says ex llpx 1512, I'd say that's the actual road number it wore before but I didn't see what road it came from.
8) I wonder if they changed-out the engine?
It had dynamic added, and I'm not sure what else, it has AC but may have always had that I can't say. It does have a new NRE tag on the side so I guess it's possible.
from a few minutes research, and providing the Blue card is correct, that should be former LLPX 1512 , CSX 1565/Conrail 1689.
The only ones I know of that had dynos were the ex C&O GP15T's. This critter look to have extended range dynos.
