US Rail Freight Declines in May Coal Shipments Drop Sharply

Data from the Association of American Railroads indicates a decline in both carload and intermodal traffic for U.S. railroads in late May. Carload traffic decreased by 10.6% year-over-year, while intermodal traffic fell by 6.5%. Coal and petroleum products experienced significant drops, while miscellaneous carloads, nonmetallic minerals, and motor vehicles & parts saw increases. Year-to-date, both cumulative carload and intermodal volumes are below last year's levels, reflecting the impact of factors such as energy transition, economic fluctuations, and supply chain challenges.
US Rail Freight Declines in May Coal Shipments Drop Sharply

Recent data reveals a concerning trend in US rail freight during late May, with both carload and intermodal volumes experiencing simultaneous declines. This unexpected downturn warrants closer examination of the underlying causes.

Key Trends in Rail Freight Performance

According to the Association of American Railroads (AAR), the week ending May 21 showed significant developments:

Overall Volume Decline:

  • Carload freight reached 244,290 units, marking a 10.6% year-over-year decrease. While lower than 2021 levels, this represents an improvement over the previous two weeks (238,353 on May 14 and 233,047 on May 7), indicating short-term volatility.
  • Intermodal containers and trailers totaled 262,693 units, down 6.5% from last year. Similar to carload figures, these numbers showed week-to-week fluctuations, being higher than May 14's 260,026 but lower than May 7's 259,876.

Diverging Commodity Performance:

Among the 10 carload commodity categories tracked by AAR:

  • Growth Categories:
    • Miscellaneous carload freight surged 20.7% to 10,071 units
    • Nonmetallic minerals increased 4.7% to 37,326 units, demonstrating resilience in construction and industrial demand
    • Motor vehicles and parts grew 2.1% to 19,067 units, signaling automotive sector recovery
  • Declining Categories:
    • Coal plummeted 28.8% to 66,709 units, representing a major drag on overall volume due to energy transition and environmental policies
    • Petroleum products fell 21.5% to 11,593 units, reflecting energy market volatility

Year-to-Date Challenges

The cumulative data from January through May 21 paints a more concerning picture:

  • Total carload freight reached 4,803,310 units, down 14% year-over-year
  • Intermodal volumes totaled 5,150,727 units, a 1.7% decrease

Root Causes of the Downturn

1. Coal's Structural Decline: The dramatic reduction in coal shipments reflects America's ongoing energy transition, with power plants increasingly adopting natural gas and renewables. Stricter environmental regulations have accelerated this trend.

2. Petroleum Market Instability: Oil-related freight declines correlate with crude price volatility, refinery capacity adjustments, and shifting demand patterns. Shale oil production uncertainties further complicate the picture.

3. Economic Headwinds: While certain sectors show growth, broader economic slowdown concerns may be suppressing freight demand, particularly in manufacturing and consumer sectors.

4. Modal Competition: Rail faces intensifying competition from trucking (for short-haul flexibility) and pipelines (for hydrocarbon cost-efficiency).

5. Supply Chain Disruptions: Global logistics bottlenecks, port congestion, and labor shortages continue creating ripple effects throughout transportation networks.

6. Intermodal Dynamics: While intermodal declines appear less severe than carload, the sector faces its own competitive pressures between truck-rail combinations and pure truck alternatives.

Strategic Considerations for Rail Operators

Industry analysts suggest several pathways for adaptation:

Data-Driven Decision Making: Enhanced analytics capabilities could help railroads better anticipate demand shifts and optimize resource allocation.

Portfolio Diversification: Reducing reliance on energy commodities by expanding into consumer goods, agriculture, and chemicals may provide stability.

Technology Investments: Automation, IoT implementations, and advanced analytics could improve operational efficiency and customer service.

Strategic Partnerships: Closer collaboration with ports, logistics providers, and freight forwarders could streamline supply chains.

Policy Engagement: Advocating for infrastructure investments and balanced regulation may help level the competitive playing field.

The US rail freight sector clearly stands at an inflection point, where proactive adaptation to market transformations will determine future success.
