Wabash was the home to a "Budd" series of dome cars for the "Bluebird" in 1950, a Pullman Standard car added in 1952, and another PS car in the last series ever built for the "City Of St Louis". Cars went on to Norfolk & Western, Central of Georgia, and Southern RY service. History of these (and all other dome cars) can be found at http://community.webtv.net/domecars/x
