Let’s explore the story behind these movements and their implications for railroads.Coal's Unexpected Rebound: A Significant Spike
U.S. rail carloads
during April and May 2025. According to the Association of American Railroads (AAR), the rise in coal shipments has been striking:In April 2025, U.S. railroads originated 53,736 more carloads of coal compared to April 2024, marking a 23.2% increase. This spike represents the largest year-over-year percentage gain in 16 months. This growth is directly linked to the export demand for U.S. coal, especially from Asia. As reported by FreightWaves, exports of coal are projected to reach 95 million short tons in 2025, up from 91 million in 2024. FreightWaves highlights that this surge is largely driven by the increased global demand for U.S. coal, particularly for power generation in energy markets.

rose by 8,809 units, bringing the total to 59,207 carloads, a 17.5% increase compared to the previous year. Even in the subsequent weeks, coal shipments remained strong, with a 6,096-carload increase for the week ending May 24, 2025.What's Fueling Coal's Comeback?
Several factors are contributing to coal’s resurgence:
- Low Base Effect: Coal volumes were exceptionally low in April and May 2024, making this year’s gains appear more substantial.
- Export Demand: The rise in demand from Asian markets, particularly China and India, is propelling coal exports.
- Energy Market Dynamics: Fluctuating natural gas prices and increased energy demand due to unseasonal weather have temporarily boosted coal’s role in power generation.
Despite this rebound, the future of domestic coal consumption remains uncertain, especially with growing environmental regulations and the rise of renewable energy sources. However, the current export strength provides a significant boost to rail traffic.
Chemicals: A Story of Sustained Strength and New Records
While coal is showing signs of life, chemicals continue to be a dominant force in U.S. freight rail. In fact, the chemical sector reached new milestones in April 2025, solidifying its position as a key player in the rail industry:
In April 2025, chemical volumes transported by U.S. railroads hit a new all-time high, with an average of 33,745 carloads per week. Year-to-date through April, chemical carloads reached 596,918, reflecting a 2.2% increase from 2024 and marking the highest volume ever for the first four months of a year. YCharts reports continued strong numbers throughout April and May, with 35,183 carloads for the week ending April 26, 2025, and 33,113 carloads for the week ending May 17, 2025.
Drivers of Record Chemical Volumes
What’s fueling these record chemical shipments? The answer lies in a mix of industrial, agricultural, and domestic factors:
- Industrial Output: A robust chemical sector often mirrors strength in manufacturing, including plastics, fertilizers, and pharmaceuticals—all of which rely heavily on rail transport.
- Agricultural Demand: The spring months typically see high demand for fertilizers, essential for farmers preparing for planting season.
- Resilient Domestic Production: Despite challenges in other manufacturing sectors, certain segments of the U.S. chemical industry remain strong, driving consistent demand for rail services.
Why These Trends Matter for Rail
The movements in coal and chemicals have important implications for the U.S. freight rail system:
- Operational Adjustments: Railroads must adjust their operations to meet the needs of specific commodities—ensuring availability of specialized railcars (e.g., covered hoppers for chemicals, open-top hoppers for coal) and managing increased capacity requirements.
- Revenue Impact: While coal volumes are increasing, chemicals provide a more consistent, high-value revenue stream for rail operators due to the nature of chemical products and their higher transportation costs.
- Economic Barometer: These commodity shifts provide insights into the broader economy—coal’s export-driven boost reflects global energy demand, while chemical rail traffic mirrors industrial and agricultural strength in the U.S.
Beyond Coal and Chemicals
While coal and chemicals dominate the headlines, other commodities are also contributing to the dynamic U.S. rail landscape. For instance, grain carloads also saw a significant uptick in April 2025, rising by 8.6% compared to April 2024, driven by strong U.S. grain exports. The AAR Rail Industry Overview for May 2025 highlights this as one of the best Aprils for rail grain since 2021, pointing to the continued importance of agriculture in rail traffic.
The diversity of commodity flows underscores the adaptability of the U.S. freight rail network, which continues to support various sectors of the economy—from coal to chemicals and beyond.
