US Rail Freight Growth Mixed As Carloads Rise Intermodal Declines

According to the Association of American Railroads, U.S. rail carloads increased by 3.4% for the week ending August 27, driven by gains in coal, grain, and motor vehicle parts. However, intermodal container and trailer volume decreased by 0.3% year-over-year. Year-to-date, carloads are up slightly by 0.1%, while intermodal volume has declined significantly by 5.3%, reflecting ongoing supply chain challenges and shifting demand patterns. This divergence highlights the complex dynamics influencing the rail freight sector and its role as an economic indicator.
US Rail Freight Growth Mixed As Carloads Rise Intermodal Declines

Imagine being an experienced navigator, where rail freight data serves as your compass through the fog of economic uncertainty. The latest U.S. rail freight statistics, released by the Association of American Railroads (AAR), present a complex picture: robust growth in carload volumes contrasted with weakening intermodal performance. What economic signals lie beneath these trends?

Carloads: The Steady Growth Engine

For the week ending August 27, U.S. rail carloads reached 242,633 units, marking a 3.4% year-over-year increase. This performance surpassed the previous two weeks (237,404 units for August 20 week and 237,857 units for August 13 week), indicating resilient demand in key economic sectors:

  • Coal: Volumes surged by 5,893 units to 74,295, reflecting sustained energy demand amid high prices and global market volatility.
  • Grain: Increased by 2,224 units to 19,458, benefiting from strong harvests and global food market needs.
  • Automotive: Rose by 1,323 units to 14,624, signaling manufacturing recovery and easing supply chain constraints.

However, several commodity groups showed declines:

  • Petroleum: Dropped by 1,228 units to 9,642, potentially indicating energy transition trends.
  • Metals: Decreased by 660 units to 23,112, possibly reflecting cooling global demand.
  • Forest Products: Fell by 419 units to 9,834, likely tied to housing market slowdowns.

Intermodal: Facing Headwinds

Intermodal containers and trailers totaled 268,941 units, representing a 0.3% year-over-year decline. While slightly better than the prior two weeks (261,144 units for August 20 week and 264,924 units for August 13 week), the sector continues to face challenges:

  • Persistent port congestion disrupting supply chains
  • Ongoing truck driver shortages limiting capacity
  • Shifting consumer demand amid economic uncertainty

Year-to-Date Trends

Cumulative data for the first 34 weeks of 2022 reveals:

  • Carloads: 7,849,281 units (+0.1% year-over-year)
  • Intermodal: 8,976,594 units (-5.3% year-over-year)

These figures underscore rail freight's continued economic importance while highlighting intermodal's particular struggles.

Economic Implications

The diverging performance between carloads and intermodal reflects broader economic dynamics. Strong commodity movements suggest resilient industrial demand, while intermodal weakness points to ongoing supply chain challenges and potential consumer pullbacks.

Looking ahead, rail operators will need to navigate shifting market conditions, while infrastructure improvements may be necessary to address systemic bottlenecks. As a key economic indicator, rail freight data continues to provide valuable insights into the nation's commercial health.
