The Roald Amundsen was the last of six Explorer-series private cars built by Pullman between 1927 and 1929. It served as the United States presidential rail car for every president from Herbert Hoover through Dwight Eisenhower. During World War II its sister car Ferdinand Magellan was rebuilt as the official presidential private car; afterwards the Roald Amundsen was sold to the New York Central Railroad as a business car. In 1971 it was donated to the McCormick-Stillman Railroad Park in Scottsdale, Arizona, and in 2009 it was placed on the National Register of Historic Places.

The car is named after the Norwegian polar explorer Roald Amundsen, one of six Explorer-series cars Pullman built between 1927 and 1929. Its sister car, the Ferdinand Magellan, was rebuilt during World War II as the official presidential private car, which pushed the Roald Amundsen into other duties.

The car can be viewed on guided tours at McCormick-Stillman Railroad Park, where other rail vehicles and family activities are also available. The park is located in Scottsdale and provides a good overview of railroad history.
