Thanks, Bruce.
The
Star had an observation car, but it was a hand-me-down from the
Meteor modified to have a diaphragm at both ends so it could run in the middle of the train. It was called a tavern-lounge (

The
Star's coaches ran on the head end, so the mid-train tavern-lounge meant those passengers didn't have to traipse the full length of the train through the sleepers -- disturbing the big-ticket passengers -- for snacks and cards. That kept the
Star from having the classic streamliner look that the
Meteor did, but it also made it the natural train to carry a private car like Jackie Gleason's.
I remember seeing the train in its later years when the dome was added. I think they got those cars from the C&O, which ordered and then discarded them for the clearance reason you mentioned north of Washington -- not only the tunnels in places like Baltimore and the Hudson River but the catenary (wires) above the tracks because that part of the railroad was electrified. It's the same reason today's Amtrak trains on the Northeast Corridor are all single-level equipment, not the double-deck equipment it uses out west.
The
Meteor ran with its sleepers on the head end and coaches on the rear, so its observation car (coach lounge) could run where it looked "right" and was adjacent to the passengers who used it (
http://www.streamlinerschedules.com/con ... 95811.html and
http://www.streamlinerschedules.com/con ... 97104.html).
Lounge space for sleeper passengers on both trains was in a sleeper-lounge car that was divided roughly half-and-half between sleeping accommodations and the lounge with its bar. But only the
Meteor got the fancy Sun Lounge cars with the big windows in the ceiling above the lounge. They were designed that way specifically for the Seaboard, without a dome, to avoid the clearance problems on the Pennsylvania Railroad, and that allowed them to run all the way to New York.
By the way, I'm curious about the operating crew change points. I think the Seaboard engineer, fireman, conductor and trainmen that boarded the southbound passenger trains in Richmond worked all the way to Hamlet. But how far south did the crew that got on in Hamlet work? When I was a brakeman in college, I only worked freight trains and never got farther north than Raleigh or farther south than Andrews or Columbia.
