US Rail Freight Sees Winter Carload Drop Amid Intermodal Growth

According to the Association of American Railroads, U.S. rail freight in February presented a mixed picture. Carload volume plummeted 11.1% year-over-year, dragged down by declining demand for coal, building materials, and automobiles. However, container traffic bucked the trend, growing by 1.8%, demonstrating the resilience of intermodal transportation. Severe weather exacerbated the challenges for traditional freight, highlighting the impact of economic restructuring and supply chain bottlenecks. Rail freight needs to actively transform, embracing intermodal solutions and digital technologies, to achieve a resurgence.
US Rail Freight Sees Winter Carload Drop Amid Intermodal Growth

Washington, D.C. – The latest data from the Association of American Railroads (AAR) reveals starkly contrasting trends in the U.S. rail freight market during February. While traditional carload freight experienced significant declines, intermodal container and trailer shipments showed remarkable growth, offering a silver lining for the industry.

Frozen Carloads: A Winter Chill for Traditional Freight

Total rail carloads plummeted 11.1% year-over-year in February to 824,636 units, representing a decrease of 102,972 carloads. This substantial drop highlights the mounting challenges facing conventional freight transportation. Key sectors showed particularly concerning declines:

  • Coal: Once the backbone of rail freight, coal shipments dropped 12.5%, reflecting America's ongoing energy transition away from fossil fuels.
  • Construction Materials: Shipments of aggregates like crushed stone, sand, and gravel plunged 33%, potentially signaling cooling infrastructure investments or seasonal factors.
  • Automotive: Vehicle and parts transportation fell sharply by 20.4%, suggesting continued supply chain challenges and shifting consumer demand in the auto industry.

Some sectors bucked the downward trend:

  • Grain: Increased 15.7%, likely driven by strong agricultural exports and global food demand.
  • Pulp & Paper: Rose 2.8%, while metal ores grew 1.4%, showing resilience in industrial sectors.

Even excluding coal, carloads still declined 10.6%. Without grain's growth, the drop would have been 14%, clearly indicating systemic challenges beyond any single commodity's performance.

Intermodal's Fiery Growth: A Logistics Revolution

In stark contrast, intermodal container and trailer shipments grew 1.8% to 1,015,995 units (up 18,184 units). This growth demonstrates intermodal's advantages in today's supply chain environment:

  • Efficiency: Seamlessly integrates rail with trucking and maritime transport
  • Cost-effectiveness: Reduces expenses through optimized routing
  • Flexibility: Adapts to diverse shipping needs
  • Sustainability: Leverages rail's lower carbon footprint

Underlying Factors: Structural Shifts Reshaping Rail

AAR Senior Vice President John T. Gray noted February's severe weather contributed to declines, but deeper transformations are reshaping rail freight:

  • Economic transition: Service and technology sectors require fewer bulk commodities
  • Energy evolution: Renewable energy growth reduces coal dependence
  • Supply chain challenges: Port congestion and labor shortages persist
  • Competition: Trucking and maritime alternatives gain market share

Rail operators are responding through:

  • Infrastructure modernization
  • Intermodal expansion
  • Digital transformation (AI, data analytics)
  • Workforce development

2021 Year-to-Date Performance

Through February, total U.S. rail carloads stood at 1,754,939 units (down 6.5% or 122,771 units), while intermodal reached 2,189,215 units (up 7.1% or 144,732 units), confirming the divergent trends.

Industry Outlook

While February's data raises concerns, rail retains strategic importance for bulk shipping and supply chain resilience. The Biden administration's infrastructure plan may provide growth opportunities through rail investments. However, operators must continue innovating to remain competitive in this evolving transportation landscape.
