US Rail Freight Intermodal Volumes Decline in Late September

For the week ending September 20, 2025, US rail freight volume decreased by 1.8% year-over-year, and intermodal volume decreased by 2.5%. Grain and metallic ores shipments increased, while coal, miscellaneous carloads, and nonmetallic minerals declined. Despite the recent downturn, year-to-date rail freight volume is up 2.2%, and intermodal volume is up 3.6% compared to 2024. Macroeconomic conditions, industry-specific factors, and supply chain issues can all influence rail transport volumes.
US Rail Freight Intermodal Volumes Decline in Late September

When the pulse of the global economy intertwines with the rhythmic clatter of railroads, even subtle fluctuations may signal underlying shifts. Recent data from the U.S. rail transportation industry has revealed a noteworthy trend—both freight volume and intermodal traffic have registered year-over-year declines. Is this a temporary adjustment or the beginning of a long-term pattern?

Current Rail Performance Metrics (Through September 20, 2025)

According to the latest figures from the Association of American Railroads (AAR), U.S. railroads reported declines in both freight carloads and intermodal units during the week ending September 20, 2025:

  • Rail freight volume: 228,609 carloads, down 1.8% year-over-year
  • Intermodal volume: 282,068 containers and trailers, down 2.5% year-over-year

Commodity-Specific Breakdown

Among the 10 major commodity categories tracked by AAR, only two showed growth compared to the same period last year:

Growth sectors:

  • Grain: 23,147 carloads (up 2,170)
  • Metallic ores and metals: 20,358 carloads (up 380)

Declining sectors:

  • Coal: 60,029 carloads (down 3,112)
  • Miscellaneous freight: 8,634 carloads (down 1,644)
  • Nonmetallic minerals: 31,402 carloads (down 736)

Intermodal Fluctuations

The 2.5% decline in intermodal traffic follows a pattern of recent volatility. The current week's volume (282,068 units) sits slightly below the previous week's 282,930 units but remains higher than the 253,497 units recorded two weeks prior.

Year-to-Date Perspective

Despite recent declines, cumulative data through the first 38 weeks of 2025 shows overall growth:

  • Rail freight: 8,423,372 carloads (up 2.2%)
  • Intermodal: 10,289,962 units (up 3.6%)

Key Influencing Factors

Several macroeconomic and industry-specific elements may be driving these transportation trends:

  • Shifting energy markets reducing coal demand
  • Agricultural commodity cycles affecting grain shipments
  • Broader economic conditions influencing manufacturing output
  • Transportation sector competition from trucking
  • Supply chain disruptions and labor availability
  • Regulatory changes impacting operational efficiency

Industry Outlook

The rail sector continues to demonstrate resilience despite recent declines, with year-to-date figures remaining positive. Industry observers note that strategic adaptation—including intermodal expansion, service diversification, and operational efficiency improvements—will be crucial for maintaining competitiveness.

As economic conditions evolve, rail operators face both challenges and opportunities. Their ability to navigate shifting market demands while investing in infrastructure and service quality will likely determine their long-term positioning in the transportation landscape.
