Harding Railroad Car, Private railroad car in Fairbanks, United States.

The Harding Railroad Car, also called Denali and numbered X-336 by the Alaska Railroad, is a Pullman passenger car displayed at Pioneer Park in Fairbanks. The Alaska Railroad bought it from the Great Northern Railway in 1923 and used it until 1945. It was restored in 1959–60 and placed in the park in 1967.

In 1923, this car carried President Warren G. Harding and his delegation to Fairbanks to celebrate the completion of the railroad line between Fairbanks and Seward. The event marked a significant milestone in Alaska's development through rail transportation.

The car displays Pullman Palace Car Company design and represents luxury standards of early railroad travel. Visitors can see today how prominent travelers were accommodated during that era.

The car stands in Pioneer Park, the city park created in 1967 for the Alaska Purchase centennial, at 64.83940, -147.77000. Look for equipment number X-336 among the park's historic buildings and rail displays. The car is a static exhibit, so plan to walk between the scattered structures rather than expect a single museum hall.

The car is one of three that carried Harding's 1923 delegation to the Mears Memorial Bridge ceremony; a separate car, The Superb, brought his remains back after his death in San Francisco. It was listed on the National Register of Historic Places in 1978.
