operates a 1950s-vintage dome car originally built by Southern Pacific on its route between Panama City and Colón alongside the Panama Canal. United States Manufacturing companies such as Colorado Railcar have built modern dome cars with updated versions of original dome design, used by American Orient Express, Holland America, Princess Tours, Alaska Railroad, Royal Caribbean, Via Rail Canada and Rocky Mountaineer Railtours. Several of the private railroad cars available for charter listed on the American Association of Private Railroad Car Owners' website have domes. Amtrak operated one dome car, #10031. It is a Budd full-length dome car, former Great Northern Railway #1391 "Ocean View" up until 2019. Painted in Phase III paint, it is used on special services such as the Oakland to Reno "Reno Fun Train", or the Seattle to Leavenworth "Snow Train". Amtrak has also operated the car in fall foliage service on the New York-Montreal "Adirondack" and on several of its Chicago-based regional trains. In the summertime, dome car #10031 is used on the single level Pacific Surfliner trainset. Another dome car Amtrak used (no longer in service) was on the Capitol Limited, possibly removed when the train switched to Superliner I & II cars. The Ocean View dome car has since been sold to Paxrail. In addition, the following railroads and tourist railways operate one or more domes: Silver Dome is on display at the Mad River and NKP Railroad Museum in Bellevue, Ohio.

It also has a former Great Northern full-length dome lounge from the former American Orient Express fleet.
