I don't know (maybe Scott M and Bob H do), but there may not have been enough inquiries/orders for justifying Amtrak cars. I'd have to go back and read all the post to even see if Amtrak had been offered, I know the data was provided.
Besides, there may always be another run if enough folks make it known they're in the market to buy and let Scott know. I think the Sun-Lounge cars would sell well no matter what name was on the side.
