I saw the Northern Pacific and Milwaukee Road one on the Super Southwest Chief, they were trailing. I found some things about them via quick Google search, I might be wrong, not that knowledgeable about old carriers. I'll leave the links.
Stampede Pass
Fleet | Paxrail
"Built as dome-coach #558 by the Budd Company in 1954 for the Chicago, Burlington, and Quincy for service on the Northern Pacific’s premier train, the Chicago-to-Seattle
North Coast Limited, which the Northern Pacific operated in partnership with the CB&Q. It operated throughout the country in Amtrak service from1971-1995 before it was sold into private ownership. The car was briefly leased to the Grand Canyon Railway, where it bore the name
Kokopelli. After the expiration of the Grand Canyon Railway lease, it operated in excursion and charter service out of Cincinnati for over a decade under the name Observatory. In the late 1990s, the car was converted from a dome-coach to a dome-sleeper, with the addition of three bedrooms, a galley, and a lounge seating area. Paxrail acquired the car in 2015 and named it
Stampede Pass. It features dome seating for 24 passengers, as well as seating in six four-top tables in the dome, 8 booth seats, and 11 leather seats in the cherry paneled long lounge, and a full galley. The car can accommodate four overnight guests as well as one staff member. Under the dome is a public lavatory as well as a crew / storeroom. Rooms B and C feature double size beds. Based in Chicago,
Stampede Pass is fully Amtrak certified and is available for charter service nation-wide."

Pacific Home
Car History - Pacific Home
"The
Pacific Home was built in December 1949 as a 10-6 sleeper (10 roomettes, 6 bedrooms) by the Budd Company in Philadelphia, PA for the Union Pacific. It was built with no car number and named the
Pacific Home, and although it was a stainless steel car, it was painted in solid UP Armour Yellow with red striping and lettering, a light grey roof, and silver trucks.The car entered normal Union Pacific passenger car service, and was used on the famous UP train
City of Los Angeles on at least one occasion (March 31, 1950). The car was originally heated with steam from a boiler in the locomotive, as was the normal practice in railroad passenger service at that time. In August of 1969, the car was numbered #1418. From its delivery, the
Pacific Home was lettered “PULLMAN” in its letterboard until the discontinuance of Pullman sleeper service in 1970, when the lettering was removed entirely, leaving only the small "UNION PACIFIC" lettering in the upper corner of the car's letterboard.
Amtrak took over all national interstate passenger service in May of 1971. With much of its passenger equipment now surplus, the Union Pacific sold the
Pacific Home to Amtrak in December of 1971. The car became Amtrak #2616 but retained its name. The
Pacific Home had its yellow paint stripped off in favor of its natural stainless steel finish, and a simple Amtrak red, white, and blue windowband was applied. The
Pacific Home ran on the first Amtrak train from New York to Montreal on September 30, 1972 and was a run-through car on the famous Southern
Crescent on at least three occasions (October 30, 1975, March 9, 1977, and April 15, 1977). In December of 1979, Amtrak completely rebuilt the
Pacific Home, re-upholstering and re-carpeting much of the interior, carpeting the walls, and removing the steam heat, replacing it with head-end power (HEP) and electric heat. The car was repainted with the newer style Amtrak windowband and renumbered #2885 at this time, and it kept this number until it was stored in September of 1995 and finally retired by Amtrak in 2001.
The car was acquired by Mercer County, NJ and moved to a disconnected piece of track at the Dempster Fire Training Center of the Mercer County Fire Academy in Lawrenceville, NJ. It was used to support fire training exercises.
Private car owner and mechanic Chuck Jensen purchased the car in 2009. The car was trucked over the road to the shop of the Morristown & Erie Railway in Morristown, NJ, and Jensen began restoring the car with the help of other mechanics. The Amtrak-applied wall carpeting was removed from the interior, and the electronics were fully upgraded. A new shower was installed, and a bathroom replaced one of the roomettes. The car now sleeps 21 people in 6 bedrooms and 9 roomettes. A generator was added so the car could power itself without power from a locomotive. The Amtrak red, white, and blue window band was removed, leaving the whole exterior in its shiny stainless steel finish with its "PULLMAN" lettering reapplied. The trucks and running gear were completely rebuilt to current Federal Railroad Administration and Amtrak standards. After over three years of work, the
Pacific Home was fully equipped to ride the rails again!"
Yerba Buena
AAPRCO and
Yerba Buena | Friends of the 261
"
The Yerba Buena, built by Pullman-Standard in 1942 as a four bedroom, four compartment and two drawing room sleeper for joint
Cities trains on the C&NW, SP and UP and named
Imperial Drive. In 1947, when the car pool was ended, the car became Chicago & North Western property. It was withdrawn from service and retired in 1965. In 1970
Imperial Drive was sold to Bill Kratville’s Auto-Liner Corporation in Omaha and was modified as private car No. 100, named
Happy Hollow. The car was sold to and ran in service for Great Western Tours and then moved on to Rail Ventures where it was renamed
Yerba Buena.
Today, the
Yerba Buena is completely self-contained, including food and beverage service, day travel capacity for up to 16 passengers, and can accommodate overnight travel for 8 passengers respectively. The Friends of the 261 have the
Yerba Buena available for charter, so individuals and groups can ride in the style once enjoyed only by railroad executives and presidents."
