https://en.wikipedia.org/wiki/Dome_car A dome car is a type of railway passenger car that has a glass dome on the top of the car where passengers can ride and see in all directions around the train. It also can include features of a coach, lounge car, dining car, sleeping car or observation. Beginning in 1945, a total of 236 were delivered for North American railroad companies. Three companies manufactured dome cars for North America: American Car and Foundry, Budd, and Pullman-Standard. In addition, the Southern Pacific Railroad constructed seven dome-lounges in its own shops.
