Drayage and intermodal both move containers, but they serve completely different purposes and cost structures. If you are importing through PortMiami or Port Everglades, choosing the wrong option can add days and hundreds of dollars to every move.
The One-Sentence Answer
Drayage is the short truck move that gets your container to or from the port — typically under 100 miles. Intermodal is the full multi-mode journey using both rail and truck together to move freight across long distances, often 500 miles or more. They are not alternatives to each other — drayage is almost always a component of intermodal.
What Is Drayage?
Drayage is the short-haul truck move of a container between a port, rail ramp, container yard, or warehouse. It is the critical first or last mile that connects ocean and rail shipping to the local destination. When a container arrives at PortMiami, the truck move that pulls it to a warehouse in Doral or Hialeah is drayage. The distance is short — usually 5 to 80 miles — but the operational complexity is high.
At PortMiami and Port Everglades, drayage involves terminal appointments, chassis sourcing, customs clearance coordination, and tight gate windows. The carrier must be licensed, insured, and familiar with the specific terminal operating system. This is not a job for a general trucking company.
When drayage is your only move
- Your cargo stays in South Florida for distribution
- Your warehouse is within 100 miles of PortMiami or Port Everglades
- You need same-day or next-day pickup from the terminal
- You are moving temperature-sensitive or hazmat freight that cannot go on rail
- You have a tight free-time window and need guaranteed appointment availability
What Is Intermodal?
Intermodal freight uses two or more transportation modes in a single journey — most commonly ocean shipping plus domestic rail plus a final truck segment. The container stays intact throughout all modes. No goods are transferred between containers, which reduces handling costs and damage risk.
In a typical intermodal move through Miami, the container arrives by ship, is drayaged to a rail ramp (CSX has a major facility in Miami), loaded onto a domestic rail car, and then drayaged again from the destination rail ramp to the final warehouse. The long-haul rail leg is where the cost savings come from.
When intermodal makes sense
- Your final destination is more than 500 miles from Miami (Atlanta, Charlotte, Dallas, Chicago)
- You have transit time flexibility — rail is 1 to 3 days slower than over-the-road trucking
- You are shipping non-hazardous, non-perishable freight
- You are moving high volume and want to reduce per-unit freight cost
- Your carbon footprint matters — rail produces 75% less CO2 per ton-mile than truck
Head-to-Head Comparison
| Factor | Drayage Only | Intermodal (Rail + Drayage) |
|---|---|---|
| Best distance | Under 200 miles | Over 500 miles |
| Typical transit time | Same day to next day | 3 to 7 days door to door |
| Cost structure | Per move, flat rate | Rail + 2x drayage fees |
| Hazmat capability | Yes (with certification) | Limited, rail restrictions apply |
| Reefer / temperature | Yes | Limited rail reefer availability |
| Visibility and tracking | Real-time GPS per truck | Rail milestone updates only |
| Flexibility on timing | High — same day available | Low — rail departures are fixed |
| CO2 footprint | Higher per mile | 75% lower per ton-mile vs. OTR |
The Intermodal Blind Spot: The Drayage Legs Still Matter
Here is what most intermodal conversations miss: the drayage legs at the origin port and destination rail ramp are often where intermodal moves fail. If your first-mile drayage carrier is slow booking a terminal appointment or cannot source a chassis, your container misses the rail cut. That one miss can add 24 to 48 hours to the entire intermodal move and eliminate the cost advantage.
Similarly, at the destination ramp, if the local trucker cannot get to the rail terminal quickly, your freight sits — and you may face rail ramp storage fees on top. This is why intermodal buyers should vet their drayage carrier as carefully as they vet their rail provider.
What About Cartage?
Cartage is sometimes confused with drayage but is a distinct service. Cartage is the local trucking of loose or palletized freight — not containerized — within a metropolitan area. It typically involves LTL pickups and deliveries within a city radius. If your freight is already devanned (unloaded from the container), the local move is cartage. If the container itself is moving, it is drayage.
South Florida Specifics: Which Mode for Which Route?
- Miami to Orlando (240 miles): Drayage wins. Rail does not make economic sense at this distance. Same-day truck delivery is achievable.
- Miami to Atlanta (660 miles): Intermodal is competitive. CSX Intermodal from Miami to Atlanta is well-served. Expect 2 to 3 day transit with drayage on both ends.
- Miami to Charlotte (750 miles): Intermodal recommended. Strong rail corridor, significant cost savings over OTR at this distance.
- Miami to Dallas (1,300 miles): Intermodal strongly favored. Cost savings are dramatic on lanes of this length.
- Miami to Chicago (1,375 miles): Intermodal wins on cost and often on transit time for non-urgent freight.
How Go Freight AI Handles Both
Go Freight AI operates the drayage leg at PortMiami and Port Everglades with owned trucks, owned chassis, and terminal-integrated dispatch. For importers with intermodal lanes, we handle the first-mile drayage from port to rail ramp with the same owned-asset reliability, ensuring you never miss a rail cut due to a chassis or appointment issue.
For South Florida distribution — Orlando, Tampa, Fort Lauderdale, West Palm Beach — we run direct truck lanes daily, and drayage is almost always the right call. For anything beyond 500 miles, we can connect you with intermodal partners and handle the origin drayage leg so you have one point of contact from port to destination.

Is drayage part of intermodal shipping?
Yes. Drayage is almost always a component of intermodal shipping. The truck move from the seaport to the rail ramp, and from the destination rail ramp to the final warehouse, are both drayage legs. Intermodal cannot happen without drayage at both ends.
When does intermodal make sense out of Miami?
Intermodal makes economic sense on lanes of 500 miles or more from Miami. For destinations like Atlanta, Charlotte, Dallas, and Chicago, intermodal via CSX can save 20 to 30 percent versus over-the-road trucking while accepting 1 to 3 days of additional transit time.
What is the CSX intermodal ramp in Miami?
CSX operates an intermodal ramp in Miami at the Hialeah yard, which connects South Florida to the broader CSX network for destinations across the Southeast, Midwest, and Northeast. Containers drayaged from PortMiami to the Hialeah ramp can connect to Atlanta, Jacksonville, Nashville, Chicago, and beyond.
Can you ship hazmat cargo via intermodal rail from Miami?
Some hazmat classes can move via intermodal rail but restrictions apply by UN number, packing group, and quantity. Class 3 flammable liquids and Class 8 corrosives have limited rail acceptance. Class 7 radioactives and certain Class 6 materials are generally prohibited. Truck drayage typically offers broader hazmat acceptance than rail intermodal.
How do drayage costs compare to intermodal costs out of Miami?
For short hauls under 200 miles, drayage-only is significantly cheaper than intermodal because you avoid the rail ramp fees and double drayage costs. For long hauls over 500 miles, intermodal total cost including both drayage legs is typically 20 to 30 percent lower than over-the-road trucking, even factoring in the additional handling.
