US Rail Freight Rises for Autos Coal As Intermodal Declines

According to the Association of American Railroads, U.S. rail traffic was mixed for the week ending September 9. Carload traffic saw a slight increase driven by demand for motor vehicles, petroleum, and coal, while intermodal volume continued its decline. For the first 36 weeks of 2023, carload traffic is up 0.1%, but intermodal is down significantly by 9.0%, resulting in a total traffic decrease of 4.8% year-over-year. This reflects ongoing challenges in the U.S. freight market.
US Rail Freight Rises for Autos Coal As Intermodal Declines

As global supply chains continue to experience uneven recovery, the US rail freight market is sending complex and nuanced signals. The latest data from the Association of American Railroads (AAR) reveals a week of contrasting trends ending September 9, with some commodity categories showing strength while others decline, raising questions about the economic outlook.

Modest Growth in Rail Freight Driven by Autos, Petroleum, and Coal

For the week ending September 9, US rail freight volume reached 218,101 carloads, marking a 0.6% year-over-year increase. While modest, this growth carries significance given current economic uncertainties. Three sectors emerged as primary drivers:

  • Motor Vehicles & Parts: The automotive sector's recovery fueled demand for rail transport, with 14,913 carloads representing a significant increase of 1,585 units compared to the same period last year.
  • Petroleum & Petroleum Products: Energy demand and refinery activity pushed this category to 9,734 carloads, up 1,416 units year-over-year.
  • Coal: Despite environmental pressures, coal maintained its position as a rail freight mainstay with 68,367 carloads, an increase of 866 units.

However, several commodity groups showed declining volumes, indicating persistent softness in certain sectors:

  • Grain: Agricultural shipments fell to 14,626 carloads, down 2,427 units, reflecting weather impacts and market conditions.
  • Nonmetallic Minerals: Construction and manufacturing demand fluctuations contributed to a decline of 679 units to 30,163 carloads.
  • Forest Products: Housing market volatility and paper industry changes led to a decrease of 514 units to 7,840 carloads.

Intermodal Decline Highlights Ongoing Supply Chain Challenges

Contrasting with the rail freight growth, intermodal traffic continued its downward trend with 229,244 containers and trailers moved during the week, representing a 3.8% year-over-year decline. This persistent weakness suggests unresolved supply chain issues including:

  • Continued port congestion despite some improvement
  • Ongoing truck driver shortages
  • Warehousing capacity constraints
  • Shifting consumer demand patterns and inventory management strategies

Year-to-Date Figures Reveal Broader Market Trends

The cumulative data for the first 36 weeks of 2023 paints a clearer picture of market dynamics:

  • Total rail carloads reached 8,071,215, showing marginal 0.1% growth
  • Intermodal volume declined sharply to 8,549,682 units, down 9.0%
  • Combined rail and intermodal traffic fell 4.8% to 16,620,897 units

Market Outlook: Balancing Challenges and Opportunities

The US rail freight sector faces a complex landscape moving forward. Potential headwinds include possible economic slowdown and constrained consumer demand. However, several factors may create growth opportunities:

  • Infrastructure investment programs
  • Electric vehicle industry expansion
  • Manufacturing reshoring trends

Rail operators will need to focus on operational improvements through automation, digital transformation, and intermodal service enhancements to maintain competitiveness during this transitional period.
