Intermodal Lags Carloads in Latest U.S. Rail Freight Data

Why It Matters

The divergence signals that while commodity‑heavy rail traffic remains resilient, intermodal’s lag exposes vulnerability to trade‑lane slowdowns and competitive trucking rates, affecting overall freight profitability.

Key Takeaways

• Intermodal units fell 2.5% week-over-week year ago
• Carloads rose 6.9% driven by grain surge
• Trans‑Pacific demand slowdown hurts intermodal growth
• Trucking rates surge, pulling volume from rail intermodal
• Canadian intermodal up 11.3%, contrasting U.S. decline

Pulse Analysis

U.S. rail carriers reported a modest 1.6% increase in total traffic for the week ending Feb. 28, reaching 516,729 carloads and intermodal units. The growth was powered primarily by a 6.9% rise in traditional carloads, buoyed by a 20% jump in grain shipments, while petroleum, chemicals and metallic ores also posted double‑digit gains. Intermodal movements, however, slipped 2.5% to 278,598 units, underscoring a divergence between bulk commodity flows and containerized freight. The eight‑week year‑to‑date picture mirrors this split, with carloads up 5.5% and intermodal down 1%.

The intermodal shortfall reflects broader macro‑economic forces. A cooling trans‑Pacific trade lane has trimmed demand for ocean‑to‑rail connections, while a tightening U.S. trucking market—characterized by soaring spot rates and driver shortages—has lured shippers toward direct truck service. This modal shift erodes rail’s share of containerized freight, especially on domestic corridors where trucks can offer faster door‑to‑door delivery. Analysts note that unless railroads enhance service reliability and pricing flexibility, the intermodal segment may continue to lag behind its carload counterpart.

For investors and industry executives, the data signals a need to recalibrate growth strategies. Rail operators may prioritize high‑margin bulk commodities such as grain and petroleum, while exploring partnerships with trucking firms to capture blended freight solutions. Meanwhile, Canadian railroads posted an 11.3% rise in intermodal volumes, suggesting regional opportunities where trade patterns differ. Monitoring the evolution of flatbed truckload rates and potential infrastructure upgrades will be crucial as rail seeks to reclaim lost intermodal market share and sustain overall freight volume growth.
