Note I was mistaken; the Blue Bird consist as delivered from Budd had four domes - and if that weren't enough, they added a P-S Dome Parlor, which resulted in five Domes for a seven car train - and with nothing much in the way of scenery (no "more smiles to the miles").
The Bluebird even had a movie (albeit, propaganda):

The Wabash also ordered one additional "streamliner", the "City of Kansas City", from ACF. No Domes.
But by the later '50's (or before I first got to Chicago on my own during 1961 - hence appropriate for this They Got Away topic) , Wabash saw the futility of these two matched trains, and they "spread" the equipment over the secondary trains, such as the "Banner Blue". Along with some PS lightweight equipment from the Boston and Maine, they largely relegated their heavyweight equipment to peak travel periods.
Incidentally, the PS Dome was sold to the Central of Georgia, and after their service got whacked on A-Day, the car was assigned to the Southern Crescent and continued there until SRY signed up with Amtrak during 1983.
The Late Mr. Ainsworth's site, "Dome Main", remains hosted by Trainweb.com and should be a source as to where these cars ended up.
