Notes: From Wikipedia: "The Atlantic Coast Line Railroad (reporting mark ACL) was a United States Class I railroad formed in 1900, though predecessor railroads had used the ACL brand since 1871. In 1967, it merged with long-time rival Seaboard Air Line Railroad to form the Seaboard Coast Line Railroad. Much of the original ACL network has been part of CSX Transportation since 1986."

White body square plate with raised or folded corners. Around the outer rim is a green repeating pattern of three small oblong leaves. At the top of the plate on the rim, under the green repeating pattern is the railroad's logo with an outer green circle containing the states served and, in the center, the stacked words "Atlantic Coast Line" in burgundy red, all-caps serif font.
