The line is still in service between Hamlet and Charleston as the Andrews Subdivision today and it is operated by Seaboard successor, CSX Transportation.

Beyond Charleston, it continued southwest through the coastal marshes of the South Carolina Lowcountry and passing through Lobeco, Levy, and into Georgia.

[3] Also in 1911, the Georgetown and Western Railroad built track from Andrews, South Carolina north to Poston and to the Pee Dee River to connect with the North and South Carolina Railway with bridge over the river being jointly owned by both companies.

Extending the Charleston Subdivision south to Savannah was quickly seen as an effective way to provide an additional freight route.

At this point, the Seaboard had a short spur from Savannah to Hutchinson Island that had been in place since 1899 to serve businesses there.

The East Carolina Line was busy enough in the 1940s to warrant the installation of Centralized traffic control signals in 1949.

[8] By 1957, at least three freight trains were running East Carolina Line round-trip from Hamlet to Savannah daily.

[7] On April 21, 1971, the Coosaw Subdivision's lift bridge over the Savannah River was destroyed when it was struck by a vessel.

However, the Seaboard Coast Line quickly determined replacing the bridge was too costly since the island could still be accessed through Coosaw despite the added distance of that route.

By then, the remaining Centralized traffic control system was decommissioned and removed and a local freight train continued to operate the Coosaw Subdivision to Hutchinson Island.

[7] In 1980, the Seaboard Coast Line's parent company merged with the Chessie System, creating the CSX Corporation.

[7] The segment of the line from East Junction in Hamlet to Charleston is still in service as CSX's Andrews Subdivision.

The center portion of the bridge including the swing span (which is locked open) remain abandoned in the middle of the river.
