SPV-2000's in Baden NC

I was in Baden NC over the weekend and came across at least 5 Budd SPV-2000 cars (ex-Conn DOT?) at the old Alcoa Aluminum plant along with a VRE diesel (GP40?). Could not get a close location for a photo. There are a few YouTube videos from about a year ago showing these cars being hauled south through Acca Yard-Richmond, but nothing since then. Anyone know why they are there and their future?
