SUPERDOME
Super Dome
The Super Dome was a dome lounge built by Pullman-Standard for the Chicago, Milwaukee, St. Paul and Pacific Railroad in 1952. The ten Super Domes were the first full-length dome cars in revenue service, first operating on the Olympian Hiawatha and Twin Cities Hiawatha in late 1952. Although a mixed blessing in passenger use, the cars garnered much publicity for the Milwaukee Road and several remain in operation.The above text is a snippet from Wikipedia: Super Dome (railcar)
