United States Rail Freight Transport Market Size & Share Analysis - Growth Trends & Forecasts (2025 - 2030)

United States Rail Freight Transport Market Trends and Insights

Surge in E-commerce-Led Intermodal Volumes

Containerised freight remains the United States rail freight transport market’s growth engine, with total intermodal units up 8.5 % year over year in 2024. Class I carriers have accelerated pop-up ramp initiatives and inland-port developments to capture e-commerce imports flowing through West Coast and Southwest gateways. Because omnichannel retailers schedule inventory replenishment in daily windows, on-time performance is becoming as vital as price. A clear outgrowth is the placement of new distribution centres on rail-served sites in secondary urban rings, which lengthens the dray leg and tilts the cost equation toward rail line-haul.

Gulf Coast Petrochemical Boom Boosting Tank-Car Traffic

Petrochemical complexes along the Texas-Louisiana coastline recorded a 4.2 % production increase in 2024, and rail shipments of chemicals rose roughly 3.5 % year over year, outpacing overall freight growth. ExxonMobil’s USD 2 billion Baytown expansion alone is raising specialty-chemical output by 40 %, driving additional inbound feedstock and outbound product moves. The planned deep-water Sea Port Oil Terminal at Freeport, Texas, approved by the Maritime Administration, will further reshape tank-car corridors by adding capacity to load 2 million barrels of crude daily. Growing traffic density is prompting carriers to invest in double-tracking and yard expansions to avoid pinch points.

Cross-Border Grain Flows from Canada to the United States

Canadian National’s grain and fertiliser revenue climbed 9 % in Q3 2024 thanks to a robust U.S. harvest. Rail grain movements from Canada to the U.S. exceeded 6.9 million metric tonnes that year, reinforcing rail’s role in cross-border trade. The single-line network created by Canadian Pacific Kansas City (CPKC) is poised to add further capacity, with a winter contingency plan targeting 685 000 tonnes weekly when Thunder Bay is ice-free ^{[1]Canadian Pacific Kansas City, “Strengthening Resiliency: 2024–2025 Winter Contingency Report,” Canadian Pacific Kansas City, cpkcr.com}. Increased throughput tightens supply-chain integration between Prairie grain elevators and Midwest processors, boosting car utilisation for carriers.

Resurgence of Domestic Coal under High Gas Prices

Temporary spikes in natural-gas prices drove a 3.2 % winter-over-winter increase in coal burn at power plants, and about 70 % of that coal moves by rail ^{[2]U.S. Energy Information Administration, “U.S. coal shipments increased slightly in 2022 as power plants replenished stockpiles,” U.S. Energy Information Administration, eia.gov}. Railroads chose to keep capacity active in the Powder River Basin, valuing optionality over immediate cost cuts. The upturn supports network economics because coal routes often subsidise mixed-freight lanes, although operators remain cautious about investing new capital in declining corridors. This behaviour suggests that cash-flow resilience, rather than long-term growth, motivates carriers to maintain coal capability.

Structural Decline in U.S. Coal-Fired Power

Coal shipments fell 13.6 % in 2024, reaching their lowest volume since 1988, and the Energy Information Administration sees coal’s share of generation sliding to 15 % by 2030. Class I carriers manage the downturn by allowing specialised coal cars to retire through attrition while redirecting capital toward diversified bulk and intermodal projects. Because coal routes historically subsidised network maintenance, their decline requires rate adjustments across other commodities, subtly affecting overall pricing power.

Service Reliability Issues Driving Mode Shift to Trucking

Journal of Commerce surveys show that many rail customers remained dissatisfied with H2 2024 performance, citing missed pick-ups and erratic transit times. Shippers warned regulators that weak rail service threatens the broader economy, prompting congressional hearings and calls for Surface Transportation Board action. Some cargo has migrated to trucking despite higher freight rates, underscoring the premium shippers place on dependability. Carriers have begun posting real-time dashboards and rehiring crews to stabilise key terminals, indicating a more proactive stance on service recovery.

Segment Analysis

Cargo Type: Intermodal Leads Growth Amid Evolving Commodity Mix

Intermodal holds a 46 % market share of the United States rail freight transport market size in 2024, reflecting the segment’s dominance as e-commerce and global sourcing reshape supply chains. Volume growth of 8.5 % in 2024 confirms that container traffic remains the primary engine of car-load expansion. Terminal productivity, rather than mainline speed, is emerging as the constraint; BNSF and Union Pacific have therefore prioritised new ramp capacity in Chicago and Phoenix to keep stack-train velocity intact.

Dry bulk is the next-largest segment, yet coal’s 13.6 % decline has shifted its internal mix toward grains and aggregates. Grain carloads rose year over year, cushioning revenue loss from coal and highlighting the importance of agricultural flows reported by the Agricultural Marketing Service ^{[3] U.S. Department of Agriculture, “Grain Transportation Report: 01-23-25,” Agricultural Marketing Service, ams.usda.gov}. Liquid bulk benefits from petrochemical output gains, while break-bulk and project cargo—though the smallest—show the fastest forecast CAGR at 7.1 % as renewable-energy components move by rail. The evolving commodity mix signals that railroads must maintain a flexible wagon fleet to manage diverse loading needs across cargo types.

Service Type: Allied Services Gain Momentum in Integrated Logistics

Transportation services account for roughly 89 % of 2024 market size, but allied services are forecast to grow at a 7.3 % CAGR through 2030. Growth in storage, transloading, and wagon maintenance reflects shippers’ demand for one-stop logistics solutions that reduce hand-offs. By bundling these services, carriers create stickier revenue streams and improve car utilisation, indirectly lifting margins.

BNSF’s Shortline Select partnership with Genesee & Wyoming demonstrates how main-line carriers leverage network reach to support smaller railroads and expand transload offerings. Railroads are also investing in predictive-maintenance software to cut repair cycle-time, freeing assets for higher-yield traffic. Together, these trends imply that allied services will outpace core haulage in revenue growth, enhancing overall industry resilience.

End-user Industry: Retail & FMCG Disrupts Traditional Dominance

Mining & Minerals commands a 22 % market share of 2024 rail freight volumes, anchored by residual coal traffic and rising shipments of critical minerals. Agriculture & Food retains a significant slice, supported by grain unit-train configurations that deliver low cost per tonne. Notably, cross-border grain expansions have strengthened this segment’s outlook.

Retail & Fast-Moving Consumer Goods is forecast to post an 8.2 % CAGR through 2030, making it the fastest-growing end-user category. Oil, Gas & Chemicals is buoyed by Gulf Coast investments, while Manufacturing & Automotive shows corridor-specific variability linked to plant schedules. This diversified demand mosaic reduces cyclicality and supports steady capital spending across the rail network.

Traction Type: Hybrid/Hydrogen & LNG Accelerates Amid Decarbonization Push

Diesel traction maintains an 81 % market share, but Hybrid / Hydrogen & LNG is projected to grow at a 10.4 % CAGR between 2025 and 2030. CSX’s prototype hydrogen locomotive, developed with CPKC, showcases the industry’s move toward lower-emission motive power.

Union Pacific’s battery-electric hybrid demonstrator targets up to 80 % fuel-efficiency gains in yard service. Early results suggest that hybridisation will scale first in switching roles before moving to mainline assignments, potentially stimulating domestic battery and hydrogen supply chains.

Destination: International Cross-border Growth Outpaces Domestic

Domestic movements represent 81 % of 2024 market size, yet cross-border traffic is forecast to expand at a 8.6 % CAGR through 2030. The CPKC network provides the only single-line rail service connecting Canada, the United States, and Mexico, trimming transit times and border delays.

A joint CPKC-CSX corridor linking Mexico, Texas, and the Southeast will add optionality for exporters and tighten service schedules. Growth in refrigerated agricultural exports and automotive near-shoring supports sustained international volume gains, implying that carriers will continue investing in customs-compliant gateways and temperature-controlled equipment.
