I saw another photo of that car a while back, where someone photographed the interior through the window from outside. It is an actual Viewliner II that was stripped inside to test this new (and hopefully now abandoned) cafe/lounge conversion layout.
Unfortunately that is a Viewliner II dining car that was ripped apart to test this new cafe car conversion nonsense. Very unfortunate after all of the effort and money that went into designing and building the new dining car fleet to see money wasted on destroying brand new equipment.
