The Astra Domes were a fleet of streamlined dome cars built by the American Car and Foundry Company ("ACF") and later by Pullman-Standard ("PS") for the Union Pacific Railroad between 1954–1958. ACF built a total of 35 cars including coaches, dining cars, and observation cars, while PS built 5 for Union Pacific. After Union Pacific exited the passenger business in 1971 the Auto-Train Corporation purchased most of the fleet and operated them for an additional ten years.
