DOMECAR
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, dome cars were primarily used in the United States and Canada, though a small number were constructed in Europe for Trans Europ Express service, and similar panorama cars are in service on Alpine tourist railways like the Bernina Express.The above text is a snippet from Wikipedia: Dome car
