US Intermodal Sets All-Time Record as Rail Freight Boom Extends

US intermodal traffic rose 9.6% year over year in October to an all-time monthly record — the third consecutive month of record volumes, according to the Association of American Railroads' latest Rail Industry Overview.

That 9.6% gain dwarfs the 4.9% growth rate recorded for the year to date. And the AAR doesn't read it as rail simply taking share from trucks. The association attributes the surge to broad industrial strength, a distinction that matters for anyone planning capacity into 2026 and beyond.

How broad is the traffic base?

Carload traffic rose 3.4% year over year in October — the largest percentage increase in eight months, the AAR said. Strip out coal and carloads climbed 4.5%, well above both the year's average and the 1.7% average posted from 2021 through 2025.

The breadth is the real story for practitioners:

• 15 of 20 carload commodity segments posted year-over-year gains in October.
• 16 of 20 segments are positive for the year to date.
• Motor vehicles and parts led October growth at 10%, running roughly flat for the full year after consistent week-over-week strength.
• The AAR's freight rail index, which excludes coal and grain, hit its second-highest level ever in October.
• For week 44, US intermodal volume was up 11% against a year ago, above the prior four-week trend of 9.6%.

When two-thirds-plus of your commodity board goes green in the same month, you're looking at an industrial economy in expansion, not a one-off lane shift.

What's driving freight from road to rail?

Bill Stephens, editor of Trains Magazine, laid out the three forces in an interview transcribed by FreightWaves: "What this says is: one, you've got that broad economic strength in the industrial economy; you've got a strong consumer economy that's helping with intermodal demand; and then also the high diesel prices and the tighter trucking capacity driving freight from truckload to rail, whether that's intermodal or in certain carload segments."

So pricing on the highway side is doing part of the work — but only part. The AAR flagged headwinds it can't ignore: inflation, rising interest rates, housing affordability pressures and weakening consumer confidence. Despite those caution flags, the association said economic indicators still point to an economy expanding at a solid pace, and it projected rail volumes to keep growing into 2027.

Measured results and projections sit side by side here, and they're worth keeping separate. The October record is fact. Growth through 2027 is the AAR's forecast, built on indicators that could still bend under the rate and consumer-confidence pressures the association itself named.

Why is Genesee & Wyoming splitting in three?

In a separate development, Genesee & Wyoming — the largest shortline holding company — will split into three regional holding companies in January. The scale involved:

• roughly 110 short lines
• 13,000 miles of track
• 2,000 customers
• about 1.5 million carloads per year, or roughly 9% of North American carload volume

Brookfield Infrastructure Partners and GIC, a Singapore-based wealth fund, took G&W private in 2019 for $8.4 billion. Stephens said the split is designed to broaden the pool of potential buyers ahead of an eventual sale, and noted that Brookfield's CEO had already cited G&W as a model for breaking large infrastructure assets into smaller, more sellable pieces.

For shortline customers and connecting Class 1 partners, a three-way split ahead of a sale means new counterparties and possibly new operating philosophies on regional territory — worth watching as the January date approaches.

What did BNSF report?

BNSF's latest results, reported through parent Berkshire Hathaway, track the industry trend. Volume was up nearly 4%, revenue rose 14%, and the railroad posted double-digit growth in both net income and pre-tax income while improving fuel efficiency. BNSF was a positive contributor to Berkshire's overall earnings even as the conglomerate's results fell short of some expectations.

Double-digit income growth alongside a 14% revenue gain puts BNSF in line with what the publicly traded Class 1s have been reporting — a sector-wide margin story, not a one-railroad anomaly.

With three record intermodal months behind it and the AAR projecting growth into 2027, the question for the year ahead is whether capacity, labor and equipment keep pace with demand the economy is already sending to the rails.
