If you move containers between the Port of Charleston and north Alabama, you have a new option. South Carolina Ports and Norfolk Southern started daily direct intermodal rail service between Charleston and Huntsville, Alabama, on Sept. 11, and the railroad is openly pitching it as an alternative to truck for port moves.
Both companies are selling the usual benefits, flexibility, speed to market and cost, and none of that is proven yet on a lane that has just launched. What is real is the reach. SC Ports already moves about 25% of its container volume by rail, with daily express service to its inland ports at Greer and Dillon and connections to Memphis, Atlanta, Birmingham, Nashville, Charlotte and Louisville. Huntsville adds the Tennessee Valley to that list, and it is not a small market.
The region is anchored by aerospace and defense, automotive manufacturing, electronics, pharmaceuticals and advanced manufacturing. The Port of Huntsville pairs its international airport with an intermodal center, Foreign Trade Zone No. 83 and the Jetplex Industrial Park, so shippers there are already set up to combine rail, air and truck.
South Carolina exported $38 billion in goods in 2024, of which $37.2 billion was manufactured products. Transportation equipment, including vehicles and tires, accounted for $19.2 billion, and imported auto parts, engines and transmissions exceeded $3.5 billion. According to the Richmond Federal Reserve, Charleston is especially exposed to two-way flows with China and Germany, its largest import origins, which matters for Huntsville-area factories sourcing components globally.
The Huntsville lane is one piece of a longer rail build-out at SC Ports. In 2025 the port completed a $55 million expansion of Inland Port Greer that lifted cargo-handling capacity by 50% and added 9,000 feet of track for longer trains. Norfolk Southern runs daily and overnight service to Greer on the I-85 corridor between Atlanta and Charlotte. For Charleston, the new connection could help pull discretionary cargo from the Tennessee Valley. Norfolk Southern says it strengthens the railroad’s position in a fast-growing Southeastern market.
What does this mean for your operations? Rail takes the line-haul on this lane, but the container still has to reach the railhead and leave the terminal, and those legs are where trucking and drayage sit. If you run or book those legs, this is a new lane to price, not one you lose. Shippers weighing it against long-haul truck to the coast should compare door-to-door time and cost, not just the rail leg, and factor in ramp cutoffs and terminal dwell at both ends. Give the service its first few months of operation before moving significant volume, and watch transit consistency more than the launch pitch.
