Superb, Private railroad car at Southeastern Railway Museum, US.

The Superb is a private railroad car at the Southeastern Railway Museum in Duluth with detailed wooden interiors and large observation windows. The car displays a complete interior with sleeping quarters, dining area, and all the fixtures needed for long journeys.

The car was built during an era when private railroad cars were a mark of progress and wealth for the most affluent travelers. Its listing on the National Register of Historic Places highlights its importance as evidence of this period of railway history.

The car carried President Warren G. Harding on a cross-country tour in 1923, and after his death it brought his body from San Francisco to Washington, D.C. In 1926 it was temporarily renamed Pope Pius XI for the Cardinal's Train from New York City to Chicago. Later it served as an office car for the Charleston and West Carolina, Atlantic Coast Line and Seaboard Coast Line railroads.
