Unusual Heritage diner sighting: non-revenue move?

Anyone know what this car was doing in Pennsylvania yesterday?

Can't see the number, but it was almost certainly a non-revenue move. I believe Chicago had one bad-ordered from the Lake Shore recently (not 100% sure, but I think it was 8554), so that may have been going back.

The car certainly looks like it could use some sprucing up! That faded Phase III stripe has got to go!
