What is Intermodal Trucking?
Intermodal trucking moves containerized freight using multiple transportation modes — typically truck and rail, or truck and ship. The truck handles the short-haul drayage pickup and delivery, while rail or ship covers the long-haul middle segment. For drivers and owner-operators, intermodal offers something rare in trucking: the ability to earn a strong income while being home every night. About 83% of intermodal drivers are small carriers and owner-operators — making it one of the most accessible segments for independent truckers.

What Is Intermodal Trucking?
Intermodal trucking is a freight transportation system that uses two or more modes of transport — truck, rail, and/or ship — to move cargo from origin to destination. The key feature of intermodal is that the freight stays inside the same container throughout the entire journey, regardless of how many times it changes from one mode to another. No unloading and reloading between legs. The container is simply lifted off a chassis, placed on a railcar or ship, then placed back on a chassis at the destination.
The trucking component of intermodal is called drayage — the short-haul moves at each end of the journey. A drayage driver picks up a loaded container from a shipper's warehouse and delivers it to a railyard or port. At the other end, another drayage driver picks up the container from the destination railyard or port and delivers it to the consignee. These drayage legs are typically under 50 miles — sometimes as short as 5 miles from railyard to warehouse.
Intermodal is one of the fastest-growing segments of freight transportation because it combines the efficiency of rail for long distances with the flexibility of trucks for local pickup and delivery. Rail is roughly four times more fuel-efficient than trucks for long-haul moves, which makes intermodal significantly cheaper than OTR trucking for shipments over 500 miles. For drivers, the appeal is different: intermodal drayage means short distances, predictable routes, and daily home time.
The intermodal industry handles over 27 million container moves per year in the United States. Major intermodal carriers include JB Hunt (the largest), Schneider, Hub Group, and XPO Logistics. But the real backbone of intermodal drayage is small carriers and owner-operators — 83% of intermodal truck drivers fall into this category.
Key Intermodal Terminology
Drayage
Short-haul truck move between railyard/port and shipper/consignee. Typically under 50 miles.
Chassis
The wheeled trailer frame that carries the container. Rented ($15-$30/day) or owned ($7K-$30K).
Intermodal Container
Standardized metal box (20ft, 40ft, or 53ft) designed to transfer between truck, rail, and ship.
Ramp/Terminal
The railyard facility where containers are transferred between trucks and trains using cranes or reach stackers.
How Intermodal Freight Moves: Step by Step
Understanding the full lifecycle of an intermodal shipment helps you see where drayage drivers fit into the process and why your role is critical:
Shipper Loads the Container
The shipper loads freight into an intermodal container at their warehouse or distribution center. The container is sealed, and a bill of lading is generated. For domestic intermodal, this is usually a 53-foot container. For import/export, it is a 20-foot or 40-foot marine container.
First-Mile Drayage (Truck to Rail/Port)
A drayage driver picks up the loaded container on a chassis and transports it to the nearest intermodal railyard or port terminal. This is the “first mile” — typically 5 to 50 miles. At the railyard, the driver checks in at the gate, the container is lifted off the chassis by a crane, and the driver departs with the empty chassis for the next move.
Long-Haul Rail or Ship Segment
The container is loaded onto a railcar (double-stack trains can carry two containers high) or a cargo ship for the long-haul segment. Rail handles the cross-country distance — Chicago to Los Angeles, for example — at a fraction of the cost of trucking. This segment can take 3-7 days depending on distance and rail schedules.
Last-Mile Drayage (Rail/Port to Consignee)
At the destination railyard or port, another drayage driver picks up the container on a chassis and delivers it to the consignee's facility. The consignee unloads the freight, and the driver returns the empty container to the railyard or to the next pickup location. This is the “last mile.”
Drop-and-Hook Is the Norm in Intermodal
Drayage Explained
Drayage is the heart of intermodal trucking. It is the short-distance truck transport of shipping containers between intermodal facilities (railyards and ports) and local origins or destinations (warehouses, distribution centers, and shipper/consignee facilities). Without drayage drivers, the entire intermodal system stops — containers pile up at railyards with no way to reach their final destinations.
There are several types of drayage moves, each with different operational characteristics:
| Drayage Type | Description | Typical Distance |
|---|---|---|
| Door-to-Ramp | Pickup loaded container at shipper, deliver to railyard | 10-50 miles |
| Ramp-to-Door | Pickup container at railyard, deliver to consignee | 10-50 miles |
| Port Drayage | Move containers between ocean ports and local facilities | 5-30 miles |
| Inter-Ramp | Transfer container between two railyards in the same metro | 5-25 miles |
| Shuttle/Repositioning | Move empty containers to where they are needed next | 5-50 miles |
Drayage pay is typically per-move (flat rate per container delivery) rather than per-mile, since the distances are so short that per-mile pricing would not cover operating costs. A single drayage move might pay $150-$400 depending on distance, market, and whether the container is loaded or empty. The goal is volume — completing as many moves per day as possible. For a deep dive, see our complete drayage guide.
Port Drayage Drivers Need a TWIC Card
Intermodal Container Sizes & Specs
Three container sizes dominate intermodal shipping. Understanding the differences matters because each requires a different chassis type and has different weight limits:
| Container | Length | Max Payload | Primary Use | Chassis Type |
|---|---|---|---|---|
| Domestic 53' | 53 feet | ~45,000 lbs | US domestic truck-rail shipments | 53-foot domestic chassis |
| Marine 40' | 40 feet | ~44,000-45,000 lbs | International import/export | 40-foot marine chassis |
| Marine 20' | 20 feet | ~47,000+ lbs | Heavy/dense international cargo | 20-foot or combo chassis |
The domestic 53-foot container is the workhorse of US intermodal. It is the same length as a standard dry van trailer, which means shippers can load it identically. These containers ride on dedicated 53-foot chassis and are primarily used for retail goods, consumer products, and general freight moving between major US cities.
Marine containers (20-foot and 40-foot) are the global standard for ocean shipping. They are built to international ISO specifications and can be loaded onto container ships, rail flatcars, and truck chassis. The 20-foot container — also called a TEU (Twenty-foot Equivalent Unit) — is the basic unit of measurement in container shipping. A 40-foot container equals two TEUs. For detailed specifications, see our container sizes comparison guide.
Overweight Containers Are a Major Issue
Intermodal Trucking Pay
Intermodal pay varies significantly based on whether you are a company driver or owner-operator, your location, the carrier you work with, and the type of intermodal freight you haul:
| Driver Type | Pay Range | Pay Structure | Notes |
|---|---|---|---|
| Company Driver | $70K-$100K/yr | Per-load, per-mile, or hourly | Benefits included. Higher end in major markets. |
| Owner-Operator (gross) | $800-$1,000/day | Percentage of gross linehaul | Before expenses. Net depends on chassis, fuel, insurance costs. |
| O/O Percentage Pay | 64%-90% | % of gross revenue per load | Higher % if you provide your own chassis. Lower if carrier provides. |
The biggest factor in intermodal pay is location. Drivers working out of the busiest rail hubs — Chicago (the largest intermodal market in the US), Los Angeles, Dallas, Atlanta, and Memphis — have the highest volume of available loads, which means more moves per day and higher daily earnings. Drivers in smaller markets may struggle to fill a full day of work.
The second biggest factor is efficiency. Since intermodal pay is typically per-move, the more moves you complete per day, the more you earn. Experienced intermodal drivers develop strategies for minimizing railyard wait times, optimizing route sequences, and avoiding peak-traffic hours — all of which directly impact daily income. For a detailed pay breakdown, see our intermodal pay guide.

Intermodal Equipment Requirements
Intermodal trucking requires some equipment that is different from standard OTR or dry van trucking. Here is what you need:
Tractor (day cab preferred) — Most intermodal drivers use day cabs since they are home nightly. A day cab is lighter than a sleeper, which gives you more payload capacity for heavy containers. Any Class 8 tractor rated for 80,000 lbs GVWR will work.
Chassis — The wheeled trailer frame that the container sits on. You can rent a chassis from a chassis pool at the railyard ($15-$30/day), lease from a chassis provider, or purchase your own ($7,000-$30,000 depending on type and condition). Owning your own chassis eliminates daily rental fees and gives you more flexibility.
Twistlocks — The locking mechanisms that secure the container's corner castings to the chassis. Some chassis have built-in automatic locking systems. Others require manual twistlocks. Always verify your locks are fully engaged before moving — an unsecured container can shift or fall off the chassis.
Insurance — Standard trucking insurance requirements apply: $1M liability, cargo insurance, and bobtail or non-trucking liability. Some intermodal carriers require additional coverage for chassis or container damage. Port operations may require additional insurance.
TWIC card (for port drayage) — Required for unescorted access to port and marine terminal facilities. Not needed if you only do railyard drayage. Costs ~$125 and takes 8-12 weeks to process. See our TWIC card guide.

Pros & Cons of Intermodal Trucking
Intermodal is not for everyone. Here is an honest assessment of the advantages and drawbacks:
Advantages
- Daily home time — most intermodal drivers are home every night
- Drop-and-hook — minimal waiting for loading/unloading
- No touch freight — containers are sealed, driver does not handle product
- Consistent freight volumes — major rail hubs have steady container flow
- Lower miles = less wear — shorter distances mean less truck wear and lower fuel costs
- Accessible to small carriers — 83% of drivers are small carriers/O-Os
Drawbacks
- Railyard wait times — congestion can mean 1-4 hours of unpaid waiting
- Chassis issues — pool chassis can be poorly maintained, causing breakdowns and inspections failures
- Overweight containers — shippers overload containers, driver bears the penalty risk
- Location dependency — must live near a major rail hub to have consistent work
- Chassis rental costs — $15-$30/day adds up to $400-$800/month in expenses
- Per-diem/detention limits — railyard delays are rarely compensated by carriers
The biggest deciding factor is usually home time vs income potential. If being home every night is your priority and you live near a major rail hub, intermodal is hard to beat. If you are willing to be away from home and want to maximize income, OTR or regional trucking may pay more per mile. For a complete comparison, see our intermodal vs OTR comparison guide and our detailed pros and cons guide.
Getting Started in Intermodal Trucking
Whether you want to drive intermodal as a company driver or start as an owner-operator, here is the path:
Determine Your Path: Company Driver or Owner-Operator
Company drivers work for a carrier (JB Hunt, Schneider, Hub Group) and are paid a salary or per-load rate. The carrier provides the truck, chassis, insurance, and loads. Owner-operators provide their own truck and may provide their own chassis, working under their own MC authority or leasing onto a carrier. Company is lower risk; O/O has higher earning potential.
Choose Your Market
Intermodal freight volume is concentrated at major rail hubs. The top intermodal markets in the US are: Chicago (by far the largest), Los Angeles/Long Beach, Dallas/Fort Worth, Atlanta, Memphis, Kansas City, and the New York/New Jersey port complex. You need to live within reasonable driving distance of a major ramp to make intermodal work.
Get Your Equipment Sorted
For owner-operators: you need a tractor (day cab preferred for weight savings), a chassis strategy (rent from pools or buy your own), and proper insurance. Startup costs for an intermodal O/O are generally lower than OTR because you do not need a trailer — but chassis costs are an ongoing expense. See our O/O startup guide.
Sign Up with Carriers or Use a Dispatcher
Major intermodal carriers (JB Hunt Intermodal, Schneider Intermodal, Hub Group) hire both company drivers and contracted owner-operators. You can also work with a dispatch service that specializes in intermodal loads. A good dispatcher knows which ramps have the best volume, which carriers pay the fastest, and how to minimize your unpaid waiting time.

How Our Dispatch Team Handles Intermodal Loads
At O Trucking LLC, we dispatch intermodal and drayage loads daily. Here is how we help our carriers maximize their intermodal operations:
Railyard coordination and scheduling
We track railyard gate hours, congestion patterns, and container availability at every major ramp. We schedule pickups and deliveries to minimize your wait time — avoiding peak congestion windows and routing you to the gate with the shortest line. Less time waiting at the ramp means more moves per day and more money in your pocket.
Multi-move route optimization
We sequence your daily moves to minimize deadhead between pickups and deliveries. When you drop a container at a consignee, we have the next pickup already lined up nearby — not across town. Efficient routing is the difference between 3 moves per day and 5 moves per day.
Carrier and chassis logistics support
We help our intermodal drivers navigate chassis pool availability, per-diem charges, container weight issues, and appointment scheduling. When a chassis has a maintenance issue at the ramp, we get it resolved with the pool operator so you are not stuck with a bad chassis and a wasted trip.

Intermodal Trucking FAQ
Common questions about intermodal trucking, drayage, container sizes, driver pay, and getting started
What is intermodal trucking?
Intermodal trucking is a freight transportation method that uses two or more modes of transport — typically truck and rail, or truck and ship — to move containerized cargo. The truck handles the short-haul pickup (drayage) from the shipper to the railyard or port, and the delivery from the destination railyard or port to the consignee. Rail or ship covers the long-haul segment in between. The freight stays in the same container the entire trip, so it never needs to be unloaded and reloaded between modes.
How much do intermodal truck drivers make?
Intermodal company drivers typically earn $70,000 to $100,000 per year depending on location, carrier, and experience. Owner-operators gross $800 to $1,000 per day on average, with percentage-based pay ranging from 64% to 90% of the gross linehaul rate. Pay varies significantly by market — drivers working out of major rail hubs like Chicago, Los Angeles, or Dallas tend to earn more due to higher volume and shorter distances between loads. Drayage drivers who can complete 3-4 moves per day often out-earn OTR drivers while being home every night.
What is the difference between intermodal and OTR trucking?
The biggest differences are distance, home time, and freight type. OTR (over-the-road) trucking involves driving long distances — often 2,000-3,000 miles per week across multiple states — and being away from home for weeks at a time. Intermodal trucking involves short-haul drayage moves, typically under 50 miles, picking up and delivering containers at railyards, ports, and shipper/consignee facilities. Most intermodal drivers are home daily. OTR drivers haul loose freight in standard trailers, while intermodal drivers haul sealed containers on chassis.
What is drayage in trucking?
Drayage is the short-distance transport of freight containers between a port or railyard and a nearby destination — typically a warehouse, distribution center, or shipper/consignee facility. Drayage moves are usually under 50 miles and are the first-mile and last-mile segments of an intermodal shipment. Drayage drivers pick up loaded or empty containers from railyards or ports, deliver them, and return for the next move. It is a critical link in the intermodal supply chain because without drayage, containers would be stranded at rail terminals and ports.
What equipment do I need for intermodal trucking?
At minimum, you need a day cab or sleeper tractor capable of pulling 80,000 lbs GVWR, a chassis (the wheeled trailer frame that carries the container), and the appropriate insurance. Chassis can be rented from chassis pools at railyards for $15 to $30 per day, or purchased for $7,000 to $30,000 depending on type and condition. You also need twistlocks (the locking mechanisms that secure the container to the chassis) and a valid CDL with appropriate endorsements. Some intermodal carriers provide chassis as part of the lease or contract.
What container sizes are used in intermodal trucking?
Three primary container sizes are used: domestic 53-foot containers (the most common in the US, with a 45,000 lb max payload), international 40-foot marine containers (the global standard for ocean shipping, 44,000-45,000 lb max payload), and international 20-foot marine containers (used for heavy or dense cargo, with a 47,000+ lb max payload despite the smaller size). Domestic 53-foot containers are identical in length to standard dry van trailers and are used primarily for truck-rail-truck moves within the US. Marine containers (20-foot and 40-foot) are used for import/export freight moving through ports.
Is intermodal trucking good for owner-operators?
Intermodal can be excellent for owner-operators who value daily home time and consistent, predictable freight. About 83% of intermodal drivers are small carriers or owner-operators. The advantages include daily home time, drop-and-hook efficiency (no waiting for loads/unloads), and steady freight volumes at major rail hubs. The downsides include railyard wait times that can cost hours of unpaid time, overweight containers, chassis maintenance issues, and being tied to specific geographic markets near railyards. The best intermodal markets for owner-operators are Chicago, Los Angeles, Dallas, Atlanta, Memphis, and Kansas City.
