Mt. Broderick was built in two months in late 1926 at the Pullman factory in Chicago, Illinois. It was one of thirty cars built on Lot 4998 to Plan 3521A.[3] It had ten sections (numbered 1 to 10) and a 12-seat lounge area (numbered 11 to 22).[4] In its normal overnight-mode, it could sleep 20, although in day-mode, it could seat a maximum of fifty-two passengers. It weighed 93 tons, due in part to its poured concrete floor; a feature unique to the Mt. Broderick. Passengers enjoyed the solarium lounge at its rear, as well as its buffet area. Polished brassfixtures were in the restroom area. Modifications to the car in 1935 included redoing the solarium, and replacing its crude blown air onto ice method of cooling to a then-modern air conditioning system.[5] It ran the "Southland" Route of the Louisville and Nashville Railroad in the 1940s and 1950s; Atlanta, Chicago, Cincinnati, Fort Wayne, and St. Louis were regular stops of the route.[6]
The Kentucky Railway Museum purchased the Mt. Broderick from the Pullman Company in 1958. It replaced the paint and carpet of the car with paint and carpet from the Pullman company, to keep it looking as it did during its active days. The car was also restored in late 1997.[7]
