The Anniversary Train is at Penn Coach Yard (minus 822, of course); 406 was at Race Street Engine Facility Sunday afternoon.

I guess this answers the question of "what's next?" for the exhibit train. Apparently, according to Matt,
The inside has been revamped by a team of dedicated employees that updated, transformed and added a slew of new displays. The 40th logos are gone and replaced with "Amtrak Exhibit Train" branding. This train will be making its first public debut since being redone at Fullerton Railroad Days 2013, May 4 and 5.Looks cool! I wonder what they did to the inside.
