The intermodal system, by the numbers

Follow the box through the data: the scale of the system, where containers enter the continent, where they head inland, how they move, and how it all performs. Filter the port ranking, toggle the volume trend, hover any chart — every figure links to its source.

Where the boxes enter

The coasts and the gateways

Almost everything starts at a marine terminal. Imports split roughly evenly between the East and West coasts now — the East has edged ahead over the past decade — with the Gulf a fast-growing tenth. A handful of gateways dominate the count.

Where they go inland

The hubs and the corridors

From the docks, boxes funnel onto a few dense rail corridors toward a short list of inland hubs — and one city towers over them all as the great interchange between the western and eastern railroads.

How they move

Mode and equipment

Most import boxes still leave the port by truck, but four in ten reach rail — and on the rails, containers have almost entirely displaced trailers, the shift that made double-stacking possible.

Inland mode split

How imports leave the port

Of import boxes at major North American ports in 2024, most still move inland by truck — but four in ten reach rail, directly or after transloading. Hover a slice for its share.

Trailers to containers

The COFC takeover

U.S. intermodal rail shifted overwhelmingly from trailers-on-flatcar (TOFC) to containers-on-flatcar (COFC) — the change that made double-stacking, and modern intermodal economics, possible.

How the system performs

Volume and efficiency

Volume tracks the economy — the 2018 peak, the 2023 freight recession, the 2024–25 recovery. And the economics rest on simple physics: a ton of freight moves hundreds of miles on a single gallon of fuel by rail.
