The locomotive was built for passenger service and was assigned to pull the ACL's mainline passenger trains such as the Florida Special and the South Wind until being retired in 1952 and donated to Jacksonville for display.

Service history

The locomotive pulled passenger trains, including the Miamian, the Florida Special, Palmetto Limited, the Southland, the South Wind and the Dixie Flyer. By the late 1940s, the railroad had dieselised its passenger trains and the locomotive was assigned to fast freight service and spent its last years in the Tampa, Florida area before 1952, the year it was retired and put into storage.[1][2]

Preservation

1504 was chosen for preservation by ACL president Champion Davis and the Head of ACL's Mechanical Department, John W. Hawthornethe. In 1960, after some years in storage, the locomotive was given a thorough mechanical overhaul and then placed on display in front of the then new ACL General Office Building in Jacksonville.[3] In 1986, CSX presented the locomotive to the city of Jacksonville, Florida. It was cosmetically restored and put on display at the Prime F. Osborn III Convention Center, where it currently resides.[4] It is the only surviving original USRA Light Pacific steam locomotive and is in almost original condition.

The locomotive was designated as a National Historic Mechanical Engineering Landmark in 1990.:8[5] It is also on the National Register of Historic Places.
