From the Association of American Railroads (AAR) AAR Data Center. Graph and excerpts reprinted with permission. Recent shifts in U.S. policies on trade and immigration have introduced volatility in financial markets and heightened uncertainty for firms. The ultimate outcomes and impacts of these policy changes remain unclear. Nevertheless, U.S. rail volumes have thus far remained stable, and many core economic indicators continue to signal underlying resilience. Railroads have long adapted to changing conditions, a legacy of resilience that continues today. emphasis added Click on graph for larger image. AAR shows the year-over-year change in carloads by category. U.S. railroads originated 1.13 million total carloads in April 2025, up 6.2% (65,524 carloads) over April 2024. That’s the largest year-over-year percentage gain in 16 months and the third largest in nearly four years. Carloads averaged 225,569 per week in April—slightly below March, but otherwise the highest since October 2024, with gains in 13 of 20 categories tracked by AAR. Through the first four months of 2025, total carloads were up 1.8% (67,282 carloads) over the same period last year, with 11 of 20 carload categories seeing gains. emphasis added And on intermodal: U.S. rail intermodal traffic, which is not included in carload counts, totaled 1.36 million containers and trailers in April 2025, up 7.4% (93,244 units) over April 2024. Weekly intermodal volume averaged 272,300 units in April 2025. The only April with higher intermodal volume was April 2021. In fact, April 2021 holds the all-time intermodal record for any month, averaging 290,955 units per week. Year-to-date intermodal volume in 2025 through April was 4.90 million units, up 8.1% (365,456 units) over 2024 and the second highest ever for the first four months of a year (again behind 2021). Intermodal volume closely tracks port activity, making it a bellwether for international trade trends. As yet, there is no apparent impact on carloads and intermodal from policy changes.
