Nashville, Chattanooga and St. Louis 576 is a 4-8-4 "Dixie" (Northern) type steam locomotive built in August 1942 by the American Locomotive Company (ALCO) of Schenectady, New York, for the Nashville, Chattanooga and St. Louis Railway (NC&StL). The locomotive was part of the technologically advanced J3 class.
During World War II, the J3s hauled heavy freight and troop trains. After the war, they were used in freight and passenger service until the early 1950s, when dwindling traffic and the onset of dieselization led to their retirement and scrapping by early 1952. No. 576, the only surviving mainline NC&StL steam locomotive, was donated to the City of Nashville, Tennessee, and put on display at the Centennial Park.
In 2019, No. 576 was moved to the Tennessee Central Railway Museum (TCRM), where it is being restored to operating condition by the Nashville Steam Preservation Society (NSPS) for use in excursion service on the shortline Nashville and Eastern Railroad. The restoration work is expected to be complete around 2025.
