In 1955-58, the Union Pacific received a total of 40 dome coaches, lounges and diners for its "City of Los Angeles" (COLA), "City of Portland" (COP), "City of St. Louis," and "Challenger" streamliners, thereafter known as "Domeliners." In 1956, the dome lounges were modified for mid-train use, and were generally positioned just ahead of the dome diner on the COLA and COP. These ACF-designed dome cars were the only ones to rival the aesthetics of the Budd dome cars operated by the CB&Q, NP, GN, DRGW and WP in the West. The cars did not operate over the Southern Pacific between Ogden and Oakland, and only briefly ran over the CNW before the UP switched to the Milwaukee Road for its Omaha-Chicago routing on October 31, 1955. In 1973, the UP sold 30 of these cars to Auto-Train. One dome coach and lounge were retained for special train, and several more have returned to the yellow fleet and operate in company excursion service.
