US Rail Freight Growth Uneven in May Key Sectors Gain

According to the Association of American Railroads, U.S. rail traffic and intermodal volumes declined year-over-year in May, although commodities like crushed stone, motor vehicles, and food products experienced growth. The AAR suggests the data reflects a mixed economic picture. Overall rail traffic volumes edged up slightly in the first five months, while intermodal volumes decreased. Future rail freight development hinges on macroeconomic conditions, supply chains, geopolitical factors, and industry transformation. The performance of specific sectors highlights the nuanced nature of the current economic environment.
US Rail Freight Growth Uneven in May Key Sectors Gain

The latest data from the Association of American Railroads (AAR) reveals a complex picture of the nation's rail freight sector, with overall declines masking surprising growth in specific industries.

Key Findings From May's Rail Data

May's rail freight statistics showed concerning declines across major metrics:

  • Rail carloads: 928,742 total units, marking a 3.7% decrease (35,821 fewer carloads) compared to May 2021
  • Intermodal units (containers/trailers): 1,102,558 units, representing a 4.3% decline (49,258 fewer units) year-over-year

Sectors Bucking the Trend

Among the 20 commodity categories tracked by AAR, seven showed positive growth, with three sectors demonstrating particularly strong performance:

  • Crushed stone, sand & gravel: 4,659 additional carloads (+5.8%) suggesting potential infrastructure acceleration
  • Motor vehicles & parts: 4,534 more carloads (+9%) indicating automotive sector recovery
  • Food products: 1,652 additional carloads (+7.1%) reflecting stable consumer demand

Struggling Industries

Several sectors experienced significant declines:

  • Grain: 13,738 fewer carloads (-13.5%) potentially due to weather and trade factors
  • Primary metal products: 5,878 fewer carloads (-15.3%) signaling manufacturing weakness
  • Petroleum products: 5,857 fewer carloads (-13.5%) possibly tied to energy market volatility

Underlying Economic Indicators

When excluding volatile coal and grain shipments, the adjusted data shows:

  • Excluding coal: 30,281 fewer carloads (-4.3%)
  • Excluding coal and grain: 16,453 fewer carloads (-2.8%)

Industry Perspective

AAR Senior Vice President John T. Gray described the data as reflecting "a mixed economic picture," noting automotive sector recovery and strong construction material shipments, while expressing concern about chemical shipments and disappointing grain volumes.

Year-to-Date Performance

The January-May 2022 cumulative data shows modest gains in rail carloads (0.2% increase, 8,490 more units) despite a 6.6% decline in intermodal units (389,799 fewer).

Looking Ahead

The rail freight sector's trajectory appears dependent on multiple factors including macroeconomic conditions, supply chain bottlenecks, geopolitical risks, and industry modernization efforts. The data suggests that while certain sectors face challenges, others demonstrate resilience in the current economic environment.
