Immediately following the 1967 merger, the newly created SCL network had 1,232 locomotives. The vast majority of the ACL roster contained EMD locomotives, while the SAL rostered Baldwin and ALCO diesels in addition to EMD models. Both railroads had purchased new freight locomotives in the 5 years leading up to the merger. Among the first new locomotives purchased by the Seaboard Coast Line were 28 GE U33B locomotives, acquired in 1967 and 1968. These were followed by 108 GE U36B locomotives between 1970 and 1972. From EMD, SCL purchased SD45 locomotives in 1968, with more to follow in 1971. SD45-2 locomotives were added in 1974. GP40 and GP40-2 locomotives were added to the fleet between 1968 and 1972 for use on through freights and other high priority freight trains. All former SAL locomotives ran for many years in the "Split-image" scheme, still in full SAL paint, but relettered and renumbered SCL. Two GP-7's 915 & 981 went from pure SAL to SCL Black without being in split-image and GP-7 944 and RS-3 1156 were never painted black, and retained their SAL paint until retired in 1976. The last operating SCL locomotive in SAL paint was GP-40 1559, former SAL 644, and was repainted at Hamlet, NC in March 1976 according to records. There were former P&N locomotives that retained their P&N scheme from 1969 until 1977, only RS-3's 1250 & 1256 and S-4 230 ever were repainted SCL black.
