US Rail Freight Gains in Carloads Loses in Intermodal

According to the Association of American Railroads, for the week ending March 19, U.S. rail carloads increased by 1.1% year-over-year, while intermodal traffic decreased by 5.7%. Coal and chemical shipments rose, while grain and petroleum product shipments declined. Total North American rail traffic also showed a downward trend, reflecting a complex and dynamic market environment. The data provides insights into the current state of freight transportation and broader economic activity.
US Rail Freight Gains in Carloads Loses in Intermodal

As global supply chains continue to falter, U.S. rail freight—a key economic barometer—paints a nuanced picture of recovery. Recent data from the Association of American Railroads (AAR) shows a 1.1% year-over-year increase in carload volume for the week ending March 19, while intermodal shipments declined by 5.7%, signaling complex market dynamics.

Carload Trends: Coal Surges as Grains and Petroleum Struggle

U.S. railroads originated 232,770 carloads during the surveyed week, marginally higher than the 232,338 carloads recorded the previous week but below the 238,870 carloads reported in early March. The sector displayed stark divergences among commodity groups:

Growth leaders: Coal dominated with 63,929 carloads (+4,182), followed by chemicals (34,178 carloads, +2,656) and nonmetallic minerals (31,151 carloads, +1,984). This reflects rebounding energy demand and industrial activity.

Declining sectors: Grain shipments plummeted by 4,014 carloads to 23,317, while petroleum products dropped 2,457 carloads to 9,181. Automotive shipments also contracted by 958 carloads to 13,953, likely due to agricultural cycles, energy market volatility, and ongoing auto industry supply constraints.

Intermodal Decline Points to Systemic Challenges

The 266,592 intermodal units moved during the week represent a concerning 5.7% annual decrease, despite slight sequential improvement from prior weeks. This persistent downturn suggests deeper logistical issues—including port congestion, trucking capacity shortages, and shifting consumer demand patterns—are hampering the critical rail-truck-ocean freight nexus.

Cumulative Data Reveals Broader Patterns

Year-to-date figures through March 19 show U.S. carloads up 3% (2,521,622 total), confirming rail's resilience as an economic backbone. However, intermodal units fell sharply by 7.1% (2,828,405 total), exposing structural vulnerabilities in multimodal logistics networks.

North American rail performance mirrored this trend, with total continental volume down 3.5% year-over-year for the week and 4% year-to-date (7,249,341 carloads/intermodal units), highlighting regional economic disparities.

Strategic Crossroads for Rail Transport

The sector faces simultaneous challenges and opportunities. While coal's resurgence demonstrates rail's continued relevance in energy logistics, intermodal weaknesses underscore the need for infrastructure upgrades and supply chain coordination.

Rail's environmental advantages—producing 75% fewer emissions than trucking per ton-mile—position it favorably as sustainability gains priority. Technological innovations in predictive maintenance, automated scheduling, and IoT-enabled asset tracking could further enhance efficiency.

Future growth will hinge on infrastructure investment, policy support for multimodal integration, and adaptive responses to e-commerce logistics demands. With strategic modernization, rail freight may yet strengthen its role in rebuilding resilient North American supply chains.
