LA-Long Beach Port Truck Dwell Stable; Rail Dwell Ticks Up

59 days—a continuation of a 15-month streak below the three-day threshold. This consistency reflects strong gate operations and reliable drayage availability at the nation's busiest container gateway. 41 days in March, signaling emerging capacity constraints in rail intermodal services. The divergence between truck and rail performance reflects broader market dynamics.

Rising long-haul trucking rates—driven by pandemic-era capacity exiting the market and heightened federal enforcement—are incentivizing shippers to shift volume toward rail, a cheaper alternative. This modal preference shift is pressuring rail operators, who recorded steady increases across freight categories in April. Port officials characterize the broader performance as "mostly consistent," but the elevated rail dwell for five consecutive months warrants attention from supply chain teams managing intermodal networks. For supply chain professionals, this data underscores two strategic implications: First, the continued fluidity of truck drayage at LA-Long Beach provides a stable foundation for import/export operations, though this advantage may not persist if drayage capacity tightens.

Second, rising rail dwell times suggest that modal arbitrage opportunities may be eroding—shippers considering a shift to rail should factor in degrading service levels, not just lower rates. The port complex remains operationally sound, but operators should monitor rail performance closely over the coming months.
