TheAstra Domes were a fleet ofstreamlineddome cars built by theAmerican Car and Foundry Company ("ACF") and later byPullman-Standard ("PS") for theUnion Pacific Railroad between 1954–1958. ACF built a total of 35 cars includingcoaches,dining cars, andobservation cars, while PS built 5 for Union Pacific. After Union Pacific exited the passenger business in 1971 theAuto-Train Corporation purchased most of the fleet and operated them for an additional ten years.
ACF produced three types of domes for the Union Pacific: coaches, dining cars, and observation cars. The ten dining cars were unique: the only dome dining cars (aside from GM'sTrain of Tomorrow) ever built for a United States railroad.[2]: 146 The cars featured seating on both levels: 18 in the upper level in booths and 18 in the lower level at tables. Also located on the lower level was a kitchen, pantry, and private dining room with seating for 10. Adumbwaiter connected the two levels.[3]: 166
The coaches could seat 24 in the dome area and an additional 36 in the lower level. The center section was given over to men's and women's lounges.[4] The lounge-observation cars were square-ended instead of the rounded-off design favored by many railroads. Like the coaches, the upper-level dome area could seat 24. In the lower level, starting at the vestibule end, was a card room (seating for five), cocktail lounge (seats for nine) and bar, stairs up to the dome level, and finally the observation area itself with seating for 19.[5]
The Union Pacific was a comparative latecomer to the dome scene when it ordered the Astra Domes from ACF in 1954; most western railroads already operated domes, some since the late 1940s.[6] ACF delivered the 35 cars to the Union Pacific in 1955 at the cost ofUS$10,000,000. The Union Pacific assigned the cars to its various transcontinental streamliners:[3]: 166
The Union Pacific found it necessary to assign a second steward to the upper-level dining area.[7]: 66 The Union Pacific gave great publicity to the novelty of dome dining cars operating betweenChicago,Portland, Oregon andLos Angeles.[8]: 213–214
Union Pacific later ordered an extra five coaches from Pullman-Standard, numbered 7011-7015 in 1958 which were assigned to the City of St. Louis. Alongside these was another dome, purchased for theWabash Railroad. This car was later leased and then purchased by theNorfolk and Western.
After the Union Pacific exited the passenger business in 1971 it sold two of the dome coaches (#7004 and #7008) to theAlaska Railroad for use on itsAuRoRa streamliner.[3]: 211 UP retained dome coach #7006 and dome lounge-observation #9004 for company use and donated dome diner #8003 to theNational Railroad Museum inGreen Bay, Wisconsin, where it remains today. The remainder of the fleet–seven coaches, nine dining cars and fourteen lounge-observation cars–were purchased by the newAuto-Train Corporation for use on theAuto-Train. After Auto-Train's bankruptcy in 1981 the fleet was sold and dispersed. Many remain in private hands, while some were reacquired by UP for use in excursions, business trains, and inspection trains as part of theUnion Pacific Heritage Fleet.
