Intermodal Shipping
A freight transportation method that uses two or more modes of transport (typically truck and rail, or truck, rail, and ocean) to move cargo in standardized containers without handling the freight itself when changing modes. The container is loaded once, then transferred between trucks, trains, and ships. Intermodal is typically 10-20% cheaper than over-the-road trucking for distances over 750 miles, though transit times are 1-2 days longer.
Real-World Example
A shipper moves a container from Los Angeles to Chicago via intermodal: a drayage truck takes the container from the warehouse to the rail yard, a train carries it 1,800 miles to a Chicago rail terminal, and another drayage truck delivers it to the final destination.
Why Intermodal Shipping Matters for Shippers
Selecting the right transportation mode can make or break your landed cost. Knowing how Intermodal Shipping fits into the broader modal landscape — truck, rail, ocean, air, or intermodal — helps you balance speed, cost, and reliability for every lane. The best freight strategies use multiple modes strategically rather than defaulting to the same option every time.
Common Questions About Intermodal Shipping
When should I choose Intermodal Shipping over other transportation modes?
The decision depends on your shipment's size, weight, urgency, origin-destination pair, and budget. Intermodal Shipping offers specific advantages in certain scenarios. Comparing total landed cost — including pickup, linehaul, handling, and delivery — across modes gives you the clearest picture.
Can I combine Intermodal Shipping with other modes?
Yes. Intermodal shipping combines multiple modes to optimize cost and transit time. For example, you might use Intermodal Shipping for the linehaul portion and truck for first-mile and last-mile delivery. Your broker can help you evaluate whether a multimodal approach makes sense for your lanes.
What are the capacity limitations of Intermodal Shipping?
Every transportation mode has weight, dimension, and volume constraints. Understanding the capacity limits of Intermodal Shipping helps you plan shipments efficiently and avoid costly reweighs, reclassifications, or equipment changes at the dock.
