Atlantic Coast Line 1504 is a 4-6-2 steam locomotive built in March 1919 by American Locomotive Company (ALCO) of Richmond, Virginia, for the Atlantic Coast Line Railroad (ACL) as a member of the P-5-A class under the United States Railroad Administration (USRA) standard. No. 1504 was assigned to pull ACL's premier mainline passenger trains during the 1920s to early 40s and even secondary passenger trains and mainline freight trains in the late 1940s until it was retired from revenue service at the end of 1952.

In 1960, No. 1504 was put on display in Jacksonville, Florida as the only original USRA Light Pacific steam locomotive to be preserved. In 1990, it was designated as a National Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers (ASME). No. 1504 was cosmetically restored three times in 1989, 1998, and 2015.

As of 2024, the No. 1504 locomotive is currently being restored to operating condition for use in excursion service on the South Central Florida Express (SCFE) shortline railroad in Clewiston, Florida as part of U.S. Sugar's (USSC) heritage tourist passenger train named the Sugar Express, where it will eventually run alongside ex-Florida East Coast Railway (FEC) No. 148.
