As someone who runs these things on the regular, I can say they have been ridden hard, put away wet, and not kept up well. With GE not in the game any longer its onto the after market for rehabbed, refurbished or cheaply made Chinese knock offs for parts and chips. They can be very cantankerous, finicky, electrical nightmare, and a general operational PIA. That's on a good day. The Rennselaer shop does a pretty remarkable job rebuilding these things and keeping them road worthy given the above handicap. Exporting something this worn out to a foreign country IMHO would not be something Amtrak should consider. Better to let them be used for parts to keep others running and when their time comes meet the scrappers torch.
