Strata-Dome
 The Strata-Domes were a fleet of five streamlined dome cars operated by the Baltimore and Ohio Railroad (B&O). The term referred both to a pair of dome cars constructed by Pullman-Standard and three Budd Company domes the B&O acquired from the Chesapeake and Ohio Railway (C&O). They were the first dome cars operated in the Eastern United States following on the success of the Chicago Burlington and Quincy Railroad's Vista-Domes in the west.
