AAR Reports 7.2% Increase in US Rail Freight Volume

WASHINGTON, D.C. – The Association of American Railroads recorded 534,256 total carloads and intermodal units across United States freight networks for the week ending October 10, reflecting a 7.2% rise compared to the corresponding period in 2025. Intermodal container and trailer volume expanded by 10.4% to reach 302,252 units, while traditional carloads totaled 232,004 units. Cross-border operational data revealed contrasting continental trends, with Mexican operators posting double-digit percentage gains while Canadian carload traffic remained flat.

What Is the Full Scope of This Development?

Eight out of ten carload commodity groups monitored by the Association of American Railroads achieved volume gains during the reporting period. Metallic ores and metals registered the sharpest growth rate at 19.7% to reach 22,048 carloads, followed by miscellaneous carloads increasing 17.4% to 10,508 units and motor vehicles and parts advancing 9.4% to 16,863 units. Decreases were concentrated in coal shipments, which fell 2.0% to 57,526 carloads, and food and non-grain farm products, which dropped 5.6% to 16,863 carloads. Across international borders, Canadian carriers handled 95,045 carloads (down 0.1%) and 71,855 intermodal containers (up 1.9%), while Mexican railroads handled 11,408 carloads (up 10.3%) and 12,839 intermodal containers (up 22.9%). Total financial revenues generated by member carriers during this individual operating week were not disclosed.

Key Development Data

How Does This Compare to Industry Trends?

Weekly volume growth across the United States outpaced mid-year operational benchmarks, where U.S. carriers recorded 526,410 total units for the week ending August 1, representing a narrower 2.4% year-over-year increase (Source: Association of American Railroads, 2025). The performance aligns with broader first-quarter results that saw U.S. carloads average 2.68 million units, up 4.2% from 2025 levels and marking the strongest start to a calendar year since 2019 (Source: FreightWaves, 2025). On an international scale, the global rail freight sector reached a valuation of USD 325.0 billion in 2025 and is projected to expand to USD 504.7 billion by 2035 at a 4.5% compound annual growth rate (Source: Grand View Research, 2025). While Canadian operators recorded modest volume growth following earlier operational instability, such as threatened Class I network shutdowns in August 2024 over crew fatigue rules, Mexican carriers expanded cross-border containerized volumes at more than double the North American average rate (Source: KFYR-TV, 2024). Independent verification of line-haul operating ratios for this reporting week was not available at time of publication.

Editor’s Analysis

The 10.4% surge in intermodal traffic confirms that cargo owners continue diverting discretionary freight from long-haul motor carriers back to rail intermodal corridors as supply chain cadence normalizes. Persistent weakness in utility coal loadings highlights ongoing generation shifts, requiring Class I operators to redeploy motive power toward automotive and industrial parts. Although bulk commodities generated the highest global revenue share in 2025, commercial railroad profitability will increasingly depend on high-frequency intermodal execution (Source: Business Research Insights, 2025).
