AAR Reports 3% Growth in US Weekly Rail Freight Volume

WASHINGTON, D.C. – The Association of American Railroads reported that U.S. rail traffic expanded by 3% year-over-year to 526,624 carloads and intermodal containers for the week ending August 8. Intermodal freight drove overall momentum with a 4.1% increase to 295,356 units, while carload traffic rose 1.8% to 231,268 units. Gains across eight of ten commodity sectors offset persistent downturns in traditional coal and automotive shipments.

What Is the Full Scope of This Development?

Eight out of ten commodity groups posted measurable volume increases during the reporting period, paced by strong demand in bulk agricultural and industrial materials. Grain loadings expanded 10.8% to 21,613 carloads, metallic ores and minerals advanced 8% to 22,955 carloads, and farm products excluding grain surged 10.4% to 17,849 carloads. Conversely, coal volume contracted 6.1% to 57,976 carloads, and automotive shipments dropped 5.7% to 15,037 carloads. Cross-border traffic showed mixed performance: Canadian railroads generated 92,100 carloads (up 8.6%) and 73,476 intermodal units (down 1.3%), whereas Mexican operators posted double-digit growth with 13,561 carloads (up 10.3%) and 14,029 intermodal units (up 13%). Cumulative U.S. traffic data for the first 30 weeks of 2026 was not disclosed in the preliminary operating release.

Key Development Data

How Does This Compare to Industry Trends?

North American weekly rail freight expansion outpaces recent European performance while trailing rapid capacity expansion in Asian corridors. For the earlier week ending March 28, 2026, total U.S. rail traffic was up just 0.5% year-over-year at 515,921 units, indicating that mid-year volume growth accelerated by 2.5 percentage points (Source: Association of American Railroads, 2026). In contrast, European state freight operations faced headwinds; Austria’s Rail Cargo Group reported an EBT loss of EUR 135.5 million in 2025, widening from EUR 24.5 million in 2024 as freight volumes dropped 4% to 26.2 billion net tonne-kilometres (Source: Rail Cargo Group, 2025). On a global scale, Indian Railways transported 1,600 million metric tonnes during 2024-2025 to surpass both the United States and Russia as the world’s second-largest rail freight network (Source: Indian Railways, 2025). Worldwide, the rail freight market was valued at USD 370.0 billion in 2025 and is projected to reach EUR 567.3 billion by 2035 at a compound annual growth rate of 5.0% (Source: Rail Market Insights, 2025).

Editor’s Analysis

The mid-year uptick in North American traffic confirms that consumer goods supply chains and bulk agribusiness continue to insulate rail carriers from ongoing structural contractions in thermal coal. Rising Mexican intermodal volumes reflect nearshoring supply chain reconfiguration along the cross-border trade axis. Long-term commercial viability across Class I railroads will hinge on capturing market share from highway trucking as global rail freight expenditure climbs toward USD 602.7 billion by 2036 (Source: Future Market Insights, 2025).
