U.S., Canada, Mexico Rail: Intermodal Growth & Commodity Trends
US freight rail traffic rises slightly in early July, showing modest gains. Carloads and intermodal units increase, signaling continued demand.

U.S. Freight Rail Traffic Shows Modest Gains in Early July
Freight rail traffic in the United States experienced a moderate uptick during the week ending July 12, 2024, according to data released by the Association of American Railroads (AAR). This report details the volume of carloads and intermodal units hauled by U.S., Canadian, and Mexican railroads. The increase indicates a cautiously optimistic outlook for the sector amid persistent economic uncertainties. The data, gathered from the major freight rail lines, provides insights into the health of various commodity markets, offering a snapshot of current shipping trends. Why is this important? Because the health of freight rail is a bellwether for the broader economy. The “how” encompasses the operational efficiency of the railroads themselves. This article will explore the trends and analyze the contributing factors, providing a comprehensive overview of the current state of North American freight rail.
U.S. Traffic Overview: Carloads and Intermodal Units Rise
U.S. freight railroads collectively transported 496,188 carloads and intermodal units during the week ending July 12, 2024, reflecting a 2.6% increase compared to the same period in the previous year. This positive trajectory was driven by both carload and intermodal traffic, key segments of the industry. Carloads, representing individual railcars carrying specific commodities, saw a notable rise of 4.1%, reaching 223,968 units. The intermodal segment, encompassing containers and trailers, also contributed to the growth, with a 1.4% increase, totaling 272,220 units. These figures signal that although the economy is not booming, there is sustained demand for goods, demonstrating that rail transportation continues to be a crucial element of the supply chain.
Commodity Performance: Coal and Chemicals Lead the Way
The AAR’s weekly data also breaks down performance by commodity groups, providing insights into the sectors driving the overall growth. Out of the ten carload commodities tracked, eight recorded increases. The leading gainers included coal, with a 4.8% jump to 58,370 carloads; chemicals, up 6.3% to 32,599 carloads; and motor vehicles and parts, which experienced a significant increase of 10.4% to 12,992 carloads. These increases suggest stronger demand in the energy, manufacturing, and automotive sectors. Conversely, forest products, showing a decrease of 1.8% to 8,253 carloads, and metallic ores and metals, declining by 0.7% to 20,229 carloads, experienced dips. These changes highlight the volatility inherent in the commodity markets and how these changes can shape the performance of the rail network.
Canadian and Mexican Railroads: Significant Growth in Intermodal Traffic
The report also encompasses the activity of Canadian and Mexican railroads. Canadian railroads saw 88,255 carloads (up 1.6%) and 74,638 intermodal units (up 9.3%). Mexican railroads experienced even more substantial gains, with 15,875 carloads (a 40.4% increase) and 10,661 intermodal units (a 12.6% increase). These numbers demonstrate an overall expansion of intermodal traffic, and show that the rail system is moving more goods, particularly for our southern neighbors. These developments may reflect increased trade activity and illustrate the growing importance of intermodal shipping within North America.
Conclusion
The latest AAR data reveals a cautiously positive trend for freight rail in North America. While overall traffic saw modest gains, the increases in specific commodity sectors like coal, chemicals, and motor vehicles signal underlying strengths in those markets. The robust growth in intermodal traffic, particularly among Canadian and Mexican railroads, underscores the growing importance of this shipping method. While the gains appear to be moderate, they indicate sustained demand and continued relevance of rail in the freight world. The industry is facing many challenges: volatile fuel costs, potential labor negotiations and ongoing supply chain disruptions. It is vital for the railroads to maintain operational efficiency, streamline processes, and enhance service offerings to remain competitive with other transportation methods. In the coming months, industry stakeholders will closely monitor economic indicators, freight volumes, and any impact of new regulations. The ability to adapt to evolving market dynamics will be key for continued success in the rail sector.
