US Rail Freight Growth Mixed As Carload Gains Offset Intermodal Losses

The US rail freight market in September 2021 saw a mixed performance with increased carload traffic but a decline in intermodal volume. Carload shipments of coal and metallic ores showed significant growth, while automobiles & parts and grain decreased. Cumulative data for the year remained strong. Key factors for future development include digital transformation, infrastructure development, expansion of service offerings, and a focus on sustainability. These strategies are crucial for adapting to evolving market demands and ensuring the long-term viability of the rail freight industry.
US Rail Freight Growth Mixed As Carload Gains Offset Intermodal Losses

The US rail freight market presented a complex picture in fall 2021, with traditional carload traffic showing steady growth while modern intermodal operations experienced declines. This divergence raises important questions about industry trends and potential supply chain impacts.

Overall Trends: Carloads Rise, Intermodal Declines

Latest data from the Association of American Railroads (AAR) reveals contrasting performance across rail freight segments for the week ending September 18, 2021 (with data collected through September 11):

  • Carload traffic: Reached 234,790 units, marking a 3.5% year-over-year increase and exceeding the previous week's 223,710 units and the 228,203 units recorded two weeks prior. This growth demonstrates the continued competitiveness of traditional rail freight in specific sectors.
  • Intermodal traffic: Totaled 270,832 containers and trailers, representing an 8.3% year-over-year decrease, though higher than the previous week's 244,900 units and the 266,212 units from two weeks earlier. The intermodal decline likely reflects supply chain bottlenecks and port congestion affecting multimodal efficiency.

Carload Breakdown: Mixed Performance Across Commodities

The carload growth wasn't uniform across all commodity categories. Of the 10 categories tracked by AAR, seven showed year-over-year increases while three declined:

  • Growth sectors:
    • Coal: Most significant increase, adding 7,232 carloads to reach 68,820 units. Rising energy prices and power generation adjustments likely contributed to this growth.
    • Metallic ores and metals: Increased by 5,203 carloads to 24,798 units, potentially reflecting manufacturing recovery and greater demand for raw materials.
    • Nonmetallic minerals: Grew by 2,054 carloads to 32,676 units, with construction sector recovery as the probable driver.
  • Declining sectors:
    • Motor vehicles and parts: Most significant drop, decreasing by 5,896 carloads to 11,709 units. The global chip shortage's impact on auto production directly affected these shipments.
    • Grain: Fell by 2,609 carloads to 19,432 units, potentially due to weather conditions and agricultural price fluctuations.
    • Petroleum and petroleum products: Decreased by 388 carloads to 10,494 units, possibly reflecting energy transition trends and changing oil consumption patterns.

Year-to-Date Performance: Strong Overall Results

Despite recent intermodal declines, cumulative data shows robust performance for US rail freight through 2021's first 37 weeks. Carload traffic reached 8,528,660 units (8% year-over-year growth), while intermodal volume totaled 10,265,525 units (10.9% increase).

Market Influencers: Challenges and Opportunities

This market divergence stems from multiple factors, including macroeconomic conditions and industry-specific structural adjustments:

  • Macroeconomic factors: Global economic recovery, inflationary pressures, supply chain bottlenecks, and labor shortages created complex impacts. While recovery boosted freight demand overall, supply constraints limited capacity utilization.
  • Industry structure: Rail operational efficiency, infrastructure quality, and technological adoption significantly affected performance. Network congestion and automation gaps potentially impaired freight efficiency.
  • Policy environment: Environmental regulations, energy policies, and trade agreements influenced market dynamics. Coal industry restrictions may reduce coal shipments, while clean energy support could boost related product transport.

Future Outlook: Transformation Required

The US rail freight sector faces crucial transformation challenges. Adapting to economic restructuring, energy transitions, and consumption pattern changes will be essential, alongside internal improvements in technology, management, and service offerings.

Key focus areas include:

  • Digital acceleration: Implementing IoT, big data, and AI technologies to enhance operational intelligence through precision scheduling, smart maintenance, and optimized resource allocation.
  • Infrastructure investment: Expanding network capacity, eliminating bottlenecks, and improving transport efficiency while strengthening intermodal hubs for seamless cross-transport coordination.
  • Service expansion: Evolving from pure freight transport to comprehensive logistics services including warehousing, distribution, and supply chain management solutions.
  • Sustainability initiatives: Adopting cleaner energy sources and reducing emissions to align with environmental policies and enhance rail's ecological profile.

The US rail freight market stands at a pivotal juncture. Success will require effectively navigating both challenges and opportunities in this era of transformation.
