Intermodal Drayage Guide: Container Transport Between Rail and Road

Intermodal Drayage Basics: How the System Works

Intermodal drayage is the truck transportation leg that connects rail terminals, ports, and distribution centers. When a container arrives at a rail terminal by train or at a port by ship, a drayage truck picks it up and delivers it to the final destination (usually a warehouse or distribution center within 100-200 miles). The reverse process moves loaded export containers from warehouses to rail terminals or ports.

The intermodal drayage market has grown significantly as railroads and shipping lines push for more truck-rail-truck movements instead of pure truck long-haul. For truckers, drayage offers a fundamentally different business model than over-the-road (OTR) trucking: shorter distances, more stops per day, home every night, and pricing based on per-move rates rather than per-mile rates.

A typical drayage driver's day includes 2-4 container moves within a 50-150 mile radius of the rail terminal or port. Each move involves picking up a container at the terminal, delivering it to a warehouse, and returning either with an empty container or deadheading back for the next pickup. Efficient drayage operators minimize empty miles by coordinating inbound and outbound container moves to create round trips.

The major rail intermodal providers are BNSF, Union Pacific, CSX, and Norfolk Southern, each operating networks of intermodal terminals across the country. The largest intermodal terminals are located in Chicago (the biggest intermodal hub in North America), Los Angeles/Long Beach, Dallas, Atlanta, Memphis, and Kansas City. Drayage demand is highest within 100 miles of these major terminals.

Drayage rates are quoted per container move, not per mile. A standard drayage move within 50 miles of a terminal pays $200-$400 per container. Moves of 100-200 miles pay $400-$800. These rates vary by market, season, and container type (20-foot, 40-foot, 45-foot, or 53-foot domestic containers). The drayage market is competitive, with thousands of small operators competing for moves, but consistent demand provides steady work for reliable carriers.

Rail Terminal and Port Operations for Drayage Drivers

Navigating a rail terminal or port facility efficiently is essential for drayage productivity. Time spent waiting in terminal queues or searching for containers is time you are not earning revenue. Understanding the terminal workflow helps you minimize time on-site.

Before arriving at the terminal, verify container availability through the railroad's or port's online system. BNSF uses the BNSF.com customer portal, Union Pacific uses Loup Logistics, CSX uses ShipCSX, and Norfolk Southern uses Thoroughbred Direct. Each system shows container status: on train, discharged to terminal, available for pickup, on hold (customs or other holds), and grounded position. Do not drive to the terminal for a container that is not available.

Terminal gate procedures vary but generally follow this pattern: approach the gate and present your driver's license, TWIC card (for port terminals), and the container booking or pickup reference number. The gate system verifies your carrier authorization, container assignment, and any appointment requirements. You receive a gate ticket with the container's yard location (a grid reference like Row A, Position 12, Stack 3).

Locate your container in the terminal yard using the grid reference on your gate ticket. Large terminals have internal road networks and signage. Follow the posted traffic patterns and speed limits (typically 5-15 MPH). When you reach your container's location, position your chassis under the container and wait for a yard crane or reach stacker to load it onto your chassis. At some terminals, you may pick up a grounded container by backing under it yourself.

Inspect the container and chassis before leaving the terminal. Check the container for visible damage, verify the container number matches your documentation, confirm the seal number matches the bill of lading, and inspect the chassis condition (tires, brakes, lights, landing gear, pin locks). Report any discrepancies to the gate before exiting. Once you leave the terminal gate, any unreported damage becomes your responsibility.

Gate wait times are the bane of drayage efficiency. Terminal congestion can result in 1-3 hour wait times during peak periods (Monday mornings, end of month, peak shipping seasons). Track your wait times and factor them into your pricing. Some terminals charge per-move fees and those fees are the same whether your gate time is 20 minutes or 3 hours. Your effective hourly rate plummets during long waits.

Chassis Management for Intermodal Drayage

Chassis management is one of the most complex operational challenges in intermodal drayage. Unlike standard dry van trucking where the trailer is permanently coupled to the tractor, intermodal operations use separate chassis that are checked out from pools, used for a container move, and returned.

Intermodal chassis pools are managed by companies like DCLI (Direct ChassisLink), TRAC Intermodal, and Flexi-Van. These pools maintain fleets of chassis at and around intermodal terminals for carriers to use. Pool membership requires a credit application and agreement to the pool's terms, including per-day usage fees.

Chassis rental fees are typically $18-$35 per day depending on the chassis type and pool. The clock starts when you check out the chassis and continues until you return it. A standard drayage move (pickup, delivery, and chassis return) that takes one day costs one day of chassis rental. A move where the container sits at the customer for 3 days before you can return the empty costs 3 days of rental. Managing per diem and chassis days is critical for drayage profitability.

Some drayage operators own their own chassis to avoid pool fees. A used intermodal chassis costs $3,000-$8,000 and lasts 10-20 years with proper maintenance. At $25/day pool rental rate, an owned chassis pays for itself in 120-320 days. The trade-off is that you must store, maintain, inspect, and register owned chassis, and you need a place to park empty chassis when they are not in use.

Chassis condition is a constant issue in pool operations. Pool chassis are used by hundreds of different drivers and are not always well maintained. Flat tires, broken lights, locked brakes, and damaged slider mechanisms are common. Always inspect pool chassis thoroughly before leaving the terminal. Reporting a defective chassis at checkout is easy. Dealing with a flat tire on the highway 50 miles from the terminal is expensive and time-consuming.

The chassis shortage that periodically plagues major intermodal markets (particularly Chicago, Los Angeles, and Savannah) can bring drayage operations to a halt. When chassis are not available at the terminal, you cannot move containers regardless of demand. Monitor chassis availability through your pool operator's online system and have contingency plans (use your own chassis, delay pickups, or redirect to alternate terminals) for chassis shortage situations.

Drayage Pricing and Revenue Optimization

Drayage pricing differs fundamentally from OTR pricing. Instead of per-mile rates, drayage uses per-move rates that account for the terminal time, driving distance, and return trip. Understanding the pricing structure helps you evaluate whether a move is profitable after all costs are considered.

The base drayage rate covers a single container move from terminal to destination (or vice versa). This rate includes the drive from the terminal to the delivery point and the return to the terminal. Rates are typically quoted based on distance zones: Zone 1 (0-25 miles): $175-$300, Zone 2 (25-50 miles): $250-$400, Zone 3 (50-100 miles): $350-$600, Zone 4 (100-200 miles): $500-$900.

Accessorial charges add revenue beyond the base rate. Common drayage accessorials include: detention (waiting at the customer for loading/unloading beyond the free time, typically 1-2 hours): $50-$75 per hour. Chassis split (picking up or dropping off a chassis at a location different from the container): $75-$150. Tri-axle chassis surcharge (when a heavy container requires a tri-axle chassis instead of a standard tandem): $50-$100. Pre-pull (picking up a container from the terminal and staging it near the delivery point for early morning delivery): $75-$150.

Per diem costs (chassis rental) eat into your profit margin and must be managed aggressively. If your base rate for a move is $300 and the customer holds the container for 3 days before emptying it, your chassis rental of $25/day x 3 = $75 reduces your effective rate to $225. Some carriers pass per diem charges through to the customer, while others absorb them. Negotiate clear per diem terms with your customers before the first move.

Volume agreements with intermodal marketing companies (IMCs) like Hub Group, J.B. Hunt Intermodal, Schneider Intermodal, and Echo Global Logistics provide consistent drayage volume at negotiated rates. These rates may be 10-15% below spot market rates, but the volume consistency and reliable payment make them attractive for carriers who need predictable revenue.

Optimize your daily revenue by minimizing empty miles between moves. The ideal scenario is delivering an inbound container to a warehouse, picking up an outbound container at the same warehouse (or one nearby), and returning the outbound container to the terminal. This round-trip efficiency doubles your revenue per drive cycle.

Compliance Considerations Specific to Intermodal Drayage

Intermodal drayage has several compliance requirements that are unique to or more critical in drayage than in OTR trucking.

Container weight verification is a critical compliance issue. The SOLAS (Safety of Life at Sea) regulation requires the verified gross mass (VGM) of every export container to be documented before it is loaded onto a vessel. As the drayage carrier, you may be asked to weigh the container at a certified scale and provide the VGM documentation. Overweight containers (exceeding the container's maximum gross weight or the road weight limit) create both safety hazards and regulatory violations.

Chassis registration and inspection requirements apply to both pool and owned chassis. Every chassis operating on public roads must have current registration (IRP for interstate chassis), annual DOT inspection, and proper lighting and reflective conspicuity markings. Pool chassis are supposed to be maintained by the pool operator, but the carrier operating the chassis is responsible for ensuring it is roadworthy. If a DOT officer finds you pulling an uninspected or defective chassis, the violation goes on your carrier record.

Hazmat containers in intermodal service must comply with all standard hazmat regulations. Placards must be properly displayed on the container and the chassis. Hazmat shipping papers must be in the cab. The driver must have a hazmat endorsement. Additionally, some intermodal terminals have specific hazmat handling procedures, designated hazmat storage areas, and restricted hazmat gate hours that differ from standard container operations.

Customs and CBP requirements for international containers include maintaining the seal integrity from port of origin to final destination. If a customs seal is broken, missing, or tampered with during drayage transport, you must report it to CBP immediately. Breaking a customs seal without authorization is a federal offense. Verify seal numbers against your documentation at every pickup and delivery.

Hours of service management in drayage is different from OTR because of the terminal wait times. Time spent waiting at a terminal gate is on-duty time (not driving time), which consumes your 14-hour on-duty window without producing revenue. A 2-hour gate wait at the start of your day reduces your available productive hours by 2 hours. Manage your appointment times and terminal arrivals to minimize wait times and protect your HOS window.
