The AAR Freight Rail Index (FRI), which measures seasonally adjusted month to-month rail intermodal shipments plus carloads excluding coal and grain, fell 0.5% in August 2025 from July 2025, its fourth decline in the past five months. Still, the index remains relatively strong: since 2008, it’s been higher than it was in August less than 15% of the time.
emphasis added

Rail intermodal volumes are closely tied to port activity (especially in the west) and the consumer side of the economy. In August, U.S. rail intermodal shipments were up 0.5% over last year. Average weekly intermodal volume in August 2025 was 284,316 containers and trailers, the most for any month since May 2021 and the most for August since 2018.

Meanwhile, year-over-year total U.S. rail carloads rose 0.7% in August 2025 over August 2024, marking six consecutive monthly gains. Eleven of the 20 major carload categories tracked by the AAR saw gains in August, the sixth straight month in which at least half the categories saw increases. Total carloads averaged 230,184 per week in August 2025, the most for any month since October 2022. In 2025 through August, total carloads were up 2.5%, or nearly 192,000 carloads, over last year.
