The Rockingham Railroad was really a subsidiary of the ACL. A lot of big railroads back then had short branch lines that had different names but were really part of the bigger company. They often got hand-me-down equipment and rolling stock from the big railroad, and the steam engine that Rockingham had probably started its working life on the Coast Line.
Another example of that near Hamlet was the Winston-Salem Southbound Railway, which ran from Winston-Salem to Wadesboro, where the line became ACL to Florence. It was jointly built (in 1910) and owned by the ACL and Norfolk & Western, to which the line connected on its northern end. Both parent railroads contributed locomotives, but they were lettered WSSB.
There is a bridge on U.S. 74 just east of Wadesboro that appears to have no reason for being there, but it's because shortly after it was built, the ACL abandoned its Florence-Wadesboro line that the bridge crossed over. The portion of the railroad from Winston-Salem to Wadesboro is -- as the result of many railroad mergers since 1910 -- jointly owned by Norfolk Southern and CSX. It still operates as Winston-Salem Southbound. Now it connects to CSX in Wadesboro and its trains operate from Winston-Salem to Hamlet.
