US Rail Freight Declines As Intermodal Gains Offset Losses

The US rail freight market is showing signs of divergence. Carload volume is down year-over-year, dragged down by commodities like coal and grain. However, intermodal transportation is growing, becoming a new growth driver. Full-year cumulative data presents a mixed picture, highlighting the impact of economic conditions, energy transition, and global trade. Moving forward, rail freight needs to embrace intermodal transportation, diversified business models, technological innovation, and strengthened partnerships to adapt to market changes. This is crucial for sustained success in a dynamic logistics landscape.
US Rail Freight Declines As Intermodal Gains Offset Losses

Imagine you're a logistics manager, anxiously monitoring your computer screen. Your responsibility is ensuring thousands of tons of cargo reach their destinations safely and on time. Rail transport, that traditional workhorse of logistics, plays a critical role in your supply chain. Yet the latest data makes you frown: U.S. rail freight volumes are showing troubling signals.

Recent data from the Association of American Railroads (AAR) reveals a tale of two markets for the week ending October 14: while traditional carload freight declined year-over-year, intermodal traffic bucked the trend with solid growth. What does this divergence mean, and how will it impact the broader logistics sector? Let's examine the numbers.

Carload Traffic: The Weakening of Traditional Rail

The data shows U.S. rail carloads totaled 225,405 for the week, down 2.0% from the same period last year. This figure also trails the previous week's 233,768 carloads (October 7) and the 235,988 recorded on September 30, signaling weakening demand for traditional rail freight.

Not all commodity categories declined. Six of the ten major commodity groups tracked by AAR showed year-over-year growth. Petroleum products led gains, adding 1,774 carloads to reach 10,583. Motor vehicles and parts increased by 955 carloads to 15,712, while miscellaneous freight rose by 809 to 8,786 carloads — reflecting strong demand in energy and automotive sectors.

However, significant declines in other categories offset these gains. Coal shipments plummeted by 4,787 carloads to 62,138. Grain volumes fell by 2,049 to 22,176 carloads, while metal ores and products decreased by 1,705 to 18,137. The coal decline mirrors energy transition trends, while grain and metal reductions may relate to global trade patterns and industrial production shifts.

Intermodal: The Emerging Growth Engine

In stark contrast, intermodal posted robust gains. U.S. railroads moved 267,376 containers and trailers during the week, up 2.8% year-over-year. This also exceeds the 265,449 units moved the prior week (October 7) and the 264,166 recorded on September 30, positioning intermodal as rail's new growth frontier.

Intermodal's strength lies in its flexibility and efficiency, combining rail's cost advantages with trucking's door-to-door capabilities. This hybrid approach proves particularly attractive for time-sensitive shipments. Additionally, intermodal reduces highway congestion and emissions, aligning with sustainability goals.

Year-to-Date Performance: A Mixed Picture

Cumulative data through the first 41 weeks of 2023 shows U.S. rail carloads at 9,234,003, up 0.3% from 2022. However, intermodal volumes of 9,862,159 units represent a 7.7% year-over-year decline. While carloads show modest growth, intermodal's slump drags down overall performance.

Underlying Factors: A Complex Web

This divergence stems from multiple intersecting forces:

Economic conditions: Macroeconomic fluctuations directly impact freight demand. Slowing growth or recession reduces shipments, while recovery stimulates them.

Energy transition: Coal's decline as a power source directly reduces rail volumes. While renewable energy creates new transport needs, these currently can't fully offset coal's retreat.

Global trade: Shifting trade policies, tariffs, and geopolitical tensions affect import/export volumes.

Supply chain challenges: Post-pandemic disruptions, port congestion, and labor shortages continue influencing rail operations.

Competition: Rail faces intensifying competition from trucking, maritime, and air freight — each offering distinct advantages in speed or flexibility.

Future Outlook: Transformation and Opportunity

To meet these challenges, U.S. rail freight must evolve:

Intermodal expansion: As the sector's growth engine, intermodal requires infrastructure investment and service improvements to attract shippers.

Diversification: Railroads must reduce reliance on coal and grain by transporting renewable energy equipment, e-commerce shipments, and other emerging cargo types.

Technology adoption: Implementing IoT, big data analytics, and AI can enhance efficiency, reduce costs, and improve customer experiences.

Collaboration: Strengthening partnerships with trucking firms and ports will create seamless, efficient multimodal networks.

The U.S. rail freight sector stands at an inflection point. While traditional carload traffic faces headwinds, intermodal's rise presents new opportunities. Only through innovation and adaptation can railroads maintain competitiveness in this evolving landscape. For logistics professionals, staying attuned to these shifts and adjusting strategies accordingly will prove essential for maintaining resilient, efficient supply chains.
