Why Rail Is Booming: Intermodal & Carload Growth Explained
U.S. rail traffic surged in week 40, with intermodal up 10.4% and carloads up 3.4% year-over-year, driven by tight trucking capacity and high diesel prices. Western railroads like BNSF and Union Pacific led gains, while Eastern carriers also saw growth. The AAR reports broad-based industrial expansion, with 17 of 20 carload categories rising in September. Risks include potential softening consumer spending if diesel prices stay high.
