Intermodal Shipping in Maryland
Maryland is a major intermodal market anchored by the Port of Baltimore and CSX's flagship intermodal hub at North Baltimore. The state's position in the mid-Atlantic corridor, combined with direct rail access from the port to inland markets, makes Maryland one of the most active intermodal states on the East Coast, handling hundreds of thousands of container lifts annually.
Industries Using Intermodal in Maryland
These industries drive Intermodal freight demand in Maryland.
Port & Maritime Logistics
The Port of Baltimore (Helen Delich Bentley Port) is the top US port for roll-on/roll-off cargo and a growing container port. The Seagirt Marine Terminal's 50-foot deep berth handles the largest containerships, with on-dock CSX intermodal rail connecting containers directly to inland markets.
Government & Defense
The Baltimore-Washington corridor hosts major federal facilities—Fort Meade (NSA), Aberdeen Proving Ground, and NIH. Government supply chain operations use intermodal for non-sensitive logistics, moving equipment and supplies between Maryland and military/government installations nationwide.
Consumer Distribution
Maryland's position between Washington, DC and the Northeast corridor makes it a prime location for regional DCs. Companies like Under Armour (Baltimore), Amazon, and national retailers receive intermodal containers from West Coast and Gulf Coast origins for mid-Atlantic distribution.
Key Intermodal Freight Lanes in Maryland
High-volume Intermodal lanes originating in or passing through Maryland.
Port of Baltimore → Chicago (CSX National Gateway)
CSX's National Gateway corridor connects Baltimore directly to Chicago and the Midwest via double-stack-cleared routes. This is the Port of Baltimore's competitive advantage—on-dock rail to Chicago in 2-3 days, avoiding the congestion of NY/NJ port drayage.
Baltimore → Ohio Valley (CSX)
CSX provides intermodal service from Baltimore to Columbus, Cleveland, and Cincinnati. This corridor serves Maryland importers and manufacturers connecting to Ohio's manufacturing and distribution markets.
Baltimore → Southeast (CSX/NS)
Southbound intermodal from Baltimore to Charlotte, Atlanta, and Jacksonville. Both CSX and NS serve this corridor, providing Maryland shippers with competitive options for Southeast distribution.
Maryland Regulations for Intermodal Freight
Key regulatory considerations for Intermodal shipping in Maryland.
Maryland Overweight Container Permits
Maryland issues special permits for overweight ocean containers moving from the Port of Baltimore to nearby distribution facilities or rail ramps. The I-695/I-95 corridor has designated heavy-container routes. Permits are processed through MDOT SHA with 24-48 hour turnaround.
Port of Baltimore TWIC & Access Requirements
All drayage drivers accessing Seagirt Marine Terminal or other port facilities must have valid TWIC credentials. The port uses an online appointment system for container pickup/delivery. Gate hours vary by terminal. The port's Sparrows Point and South Locust Point terminals have separate access procedures.
Market Insights: Intermodal in Maryland
On-Dock Rail Advantage
Baltimore's Seagirt Terminal offers on-dock CSX rail—containers can move from ship to train without a drayage truck touch. This on-dock connection eliminates the $300-$500 per container drayage cost that NY/NJ port users face, making Baltimore increasingly competitive for Midwest-bound import containers.
Howard Street Tunnel Clearance
CSX's Howard Street Tunnel in downtown Baltimore is being expanded to accommodate double-stack container trains. Once complete, this will dramatically increase the volume of intermodal containers that can move through Baltimore on the CSX National Gateway, further strengthening Maryland's position as an East Coast intermodal hub.
Intermodal Shipping in Maryland — FAQs
Where are Maryland's intermodal terminals?
Maryland's primary intermodal facilities include CSX's North Baltimore intermodal terminal (one of the largest on the East Coast), the Port of Baltimore's Seagirt Marine Terminal with on-dock CSX rail, and NS connections in the Baltimore area. These facilities handle domestic intermodal containers and ocean containers with direct rail service to inland markets.
What is the Howard Street Tunnel project?
CSX is expanding the 130-year-old Howard Street Tunnel in downtown Baltimore to accommodate double-stack intermodal container trains. The current tunnel limits train height, forcing single-stack operations. Once complete, the expanded tunnel will allow taller double-stack trains, increasing Baltimore's intermodal capacity and reducing costs for containers moving through the CSX National Gateway.
How does Baltimore compete with NY/NJ for intermodal?
Baltimore competes by offering on-dock rail (no drayage needed from port to rail), less congestion than NY/NJ, competitive port fees, and CSX's National Gateway corridor to the Midwest. For Chicago-bound import containers, Baltimore can be faster and cheaper than NY/NJ. The Howard Street Tunnel expansion will further strengthen this advantage.
What are intermodal transit times from Baltimore?
From Baltimore CSX: 2-3 days to Chicago, 2 days to Columbus/Cleveland, 1-2 days to Charlotte, 2-3 days to Atlanta, 4-5 days to Los Angeles. Baltimore's direct CSX mainline access provides competitive transit times, particularly to Midwest destinations where the National Gateway corridor offers efficient double-stack service.
