The Atlantic Coast Line P-5-A was a class of 70 4-6-2 USRA Light Pacific steam locomotives built by the American Locomotive Company's Richmond and Brooks Works between 1919 and 1920 for the Atlantic Coast Line Railroad (ACL) to haul their premier main line passenger trains. By the early 1950s, all of the P-5-As were retired and scrapped with exception of No. 1504, who survived into preservation and is currently undergoing restoration to operating condition.
