Word is that she is getting wired together, but I'm not sure with what purpose (other than as a switcher perhaps). The power for thomas is not a bad guess though.
And as you can see by the pictures she is sharing a stall with the 484. There hasn't been any work to speak of done to the 484 in some time though. As you can see the boiler jacketing is only partially installed and it is completely sans cab.
The 463 is sporting some new accessories, and her tender lettering has been removed, so maybe she will see some movie action sometime soon.
