U.S. Rail Volume Surges 4.2% as Grain, Chemicals Drive Growth

Key Details U.S. rail traffic reached 511,216 carloads and intermodal units for the week ending May 16, marking a 4.2% increase year-over-year. Weekly carload shipments totaled 230,497 units, up 0.6% annually, while intermodal volume jumped to 280,719 containers and trailers, outpacing last year by 7.3%. Commodity Winners Seven of 10 tracked commodities showed improvement. Grain led the charge with a robust 14.5% increase, followed by petroleum products at 9.8%. Forest products posted a notable 14.5% jump, a first-time improvement that signals recovery in the residential housing sector. Where Weakness Persists Coal shipments declined 6.2% year-over-year, while nonmetallic minerals dipped 0.4%. These declines reflect ongoing softness in traditional rail categories. Broader 2026 Trends Through the first 19 weeks of 2026, U.S. railroads logged 4,297,732 carloads, up 3.4%, and 5,262,810 intermodal units, up 0.9%. North American rail volume across nine reporting railroads rose 4.2% for the week, with total combined traffic reaching 716,194 units. Why It Matters Strong grain and chemical demand is supporting overall rail performance, which can ease pressure on truck capacity and potentially benefit trucking rates during peak seasons.
