After World War II in the late 1940’s, the Pullman Company was busy building new streamlined cars for America’s railroads. Their fleet of heavyweight cars were being used in secondary trains, as well as held in reserve for heavy-volume periods for charters and ‘specials’. These heavyweight cars were painted the fleet colors of the time, so when used would blend into the trains consist. The cars were very often interchanged and run in ‘specials’ creating a most interesting colorful train! I have photos of Pennsy cars in the consist of many different railroads crack passenger trains. Issues of the UPHS Streamliner show UP trains with a string of Tourist Sleepers on the end painted in the colors of L&N, ACL, and Pennsy.
