I wonder if there is interest in GGD offering a few of the "heritage" cars in Amtrak as add on cars to the Slumbercoaches. Diner, 10-6, Maybe a short dome or blunt end obs from the B&O sets in Amtrak paint.
Did you happen to order the Amtrak 3/4 dome? If so did you see that price increase from the full dome done 2 years ago! Do you think there would be enough buyers of a heritage diner and sleeping cars to keep the final car cost down?
