US Intermodal Traffic Surges as Shippers Flee Trucking Rates

US shippers are increasingly turning to intermodal transportation as an alternative to trucking amid capacity constraints and elevated truckload rates. While this represents a tactical response to market pressures, enthusiasm for the mode appears to be cooling as operational challenges emerge—particularly slower train speeds and inconsistent pick-up and delivery reliability. The article frames this shift as a return to historic norms rather than a structural market transformation, suggesting that without service-level improvements from rail operators, the mode may struggle to retain shipper interest even as economic incentives persist.

For supply chain professionals, this dynamic underscores a critical tension: cost arbitrage alone is insufficient to drive sustained mode shift. Shippers will default to trucking if rail service becomes unreliable, regardless of pricing advantages. This has implications for demand planning, carrier selection, and contingency capacity—particularly as volumes are projected to rise in fall months.

Organizations relying on intermodal strategies must actively monitor rail operator performance and build flexibility into routing logic to avoid service disruptions.
