AAR Reports 3.5% Traffic Growth Across US Rail Network

WASHINGTON, D.C. – The Association of American Railroads reported that U.S. rail traffic expanded 3.5 percent year-over-year to 514,080 total units for the week ending October 31. Total carloads reached 233,816, reflecting a 3.0 percent rise, while intermodal volume climbed 3.9 percent to 280,264 containers and trailers. Seven of the ten tracked commodity groups posted net increases during the reporting period.

What Is the Full Scope of This Development?

Total weekly rail traffic reached 514,080 units as intermodal movements outpaced conventional carload freight across U.S. networks. Metallic ores and metals recorded the sharpest commodity gain, rising 18.3 percent to 25,059 carloads, followed by motor vehicles and parts, which increased 9.1 percent to 16,628 carloads. Chemicals also advanced 7.9 percent to 34,523 carloads. Conversely, three commodity categories contracted: miscellaneous carloads dropped 12.2 percent to 8,369, grain declined 8.3 percent to 23,078, and coal edged down 0.4 percent to 55,042 carloads. Carrier-specific revenue yields and commodity ton-mile totals were not disclosed in the weekly statistical release.

Key Development Data

How Does This Compare to Industry Trends?

The 3.5 percent weekly volume growth aligns with broader North American rail momentum reported earlier in the autumn corridor cycle. By comparison, U.S. railroads recorded a 5.1 percent traffic increase for the week ending October 3, 2026, driven by a 7.4 percent jump in intermodal volume to 299,001 units and a 2.4 percent carload gain to 230,711 units (Source: Association of American Railroads, 2026). Cumulative U.S. volumes across the first 39 weeks of 2026 reached 8,910,593 carloads, up 2.7 percent, alongside 11,077,697 intermodal units, up 4.2 percent (Source: American Journal of Transportation, 2026). On a global scale, the total rail freight sector stood at USD 370.0 billion in 2025 and is projected to expand to USD 388.5 billion in 2026, with bulk and conventional carload freight maintaining a 51.37 percent market share (Source: Global Market Insights, 2025). Independent verification of line-haul margin shifts during this specific weekly period was not available at time of publication.

Editor’s Analysis

Industrial carload components, specifically metals and automotive shipments, are currently compensating for continuing sluggishness in agricultural grain traffic and structural erosion in domestic coal. The steady dominance of intermodal containers mirrors long-term supply chain realignment toward containerized inland distribution, which underpins the global cross-border rail freight market’s projected 5.10 percent compound annual growth rate through 2036 (Source: Future Market Insights, 2025). Class I operating models will depend on sustaining this automotive and chemical momentum to preserve gross network margins through the fourth quarter.
