Industry Summary
The 615 railroads in the US transport cargo within a rail network, and include line haul railroads and short line railroads. Major types of rail freight include energy products (18% of industry freight revenue), motor vehicles and equipment (17%), food and beverage products (15%), chemicals (10%) and plastics and rubber (10%). Non-freight related revenue includes fees for rail car switching, rail car hire and rental services, and demurrage (when shippers or receivers hold railcars beyond the contracted period of time).
High Capital Requirements
Rail transport is a highly capital-intensive industry, with most companies having significant investments in tracks, terminals, underlying property, locomotives, and rail cars.
Competition From Alternative Carriers
Railroads compete with alternative modes of transportation, such as trucks, barges, ships, and pipeline operators.
Recent Developments
Jan 13, 2026 - Railroad Merger to Shake Up Regional Intermodal Routes
- Union Pacific’s proposed $85 billion acquisition of Norfolk Southern would accelerate transit times on select high-volume intermodal routes while creating delays and capacity risks elsewhere. The combined company plans to invest more than $1 billion in track, yard, and terminal upgrades to support new single-line services, including a Southern California-to-New Jersey route bypassing Chicago, and faster lanes linking the Gulf Coast and Northeast. Several terminals would see major expansions to handle sharp volume increases. However, other locations would face large traffic gains with little or no new investment, raising concerns about congestion and longer container dwell times. Some shippers, particularly those moving freight from Southern California to Memphis and St. Louis, would lose direct service and face added layovers. Rival railroads argue the merger application downplays these trade-offs, prompting regulators to review whether the filing adequately addresses potential service degradation.
- The US railroad industry is showing conflicting economic signals, according to new data from the Association of American Railroads (AAR). Freight volumes are holding steady in some areas, particularly agricultural shipments and intermodal traffic, suggesting resilience in consumer demand and global trade flows. However, carloads tied to manufacturing, energy production, and construction materials are down, reflecting broader industrial weakness. The uneven performance highlights how railroads are caught between sectors still expanding and those slowing under tighter financial conditions. Industry analysts say the mixed trends point to a “plateau” rather than a downturn, with carriers adapting through efficiency improvements and cost control. While railroads are unlikely to see a major rebound without stronger industrial activity, steady intermodal demand and grain exports are helping to stabilize operations. The sector’s performance has become a key indicator of shifting economic momentum across US supply chains and heavy industry.
- Amtrak debuted the Acela NexGen high-speed train service in August 2025, which travels between Boston and Washington DC - with stops in Philadelphia, Baltimore, and New York City along the way - at speeds of up to 160 mph. It is 10 mph faster and has 27% more capacity than the last generation of Axcela trains that launched in 2000. Amtrak has plans to roll out 27 additional NexCen trains, all assembled in upstate New York, by the end of 2027. While the train is the fastest in the US, it lags far behind high-speed rail capabilities in Asia and Europe, primarily due to the fact that centuries old rail lines in the US wind through populated Northeastern communities. Amtrak has high hopes for its next generation of high-speed trains, as the last time it debuted faster rail capabilities 25 years ago, the company doubled in market share.
- The federal government’s decision to cancel a $63.9 billion planning grant for the Texas Central Railway (TCR) project, a high-speed rail line between Houston and Dallas, will instead have to move forward as a private-sector project. The project is designed to cover the 240 mile trip between the cities in 90 minutes. Since it was proposed in 2009, TCR has faced resistance from state lawmakers, struggled to obtain the land necessary to build the line, and seen its original $12 billion cost estimate skyrocket to roughly $40 billion, according to the Department of Transportation. Once the grant was pulled the project’s lead investor, Fort Worth-based Kleinheinz Capital Partners, plans to move forward with the rail line as a private venture. TCR says it has acquired about 25% of the land necessary to push the project forward and that any new investment will be sought out in the private sector.

Industry Structure
Industry size & Structure
The US freight rail transportation industry consists of 615 railroads, which employ 153,000 workers and generate $64.5 billion annually in freight revenue.
- The Association of American Railroads (AAR) classifies rail operators into one of three categories: Class I, regional, and local. Six Class I railroads generate revenue about 96% of industry revenue each year. Regional and local railroads account for the rest.
- Collectively, railroads operate nearly 140,000 miles of track.
- The industry is concentrated at the top; the top seven Class I railroads account for 94% of industry revenue.
- The seven Class I railroads are Union Pacific, CSX Transportation, BNSF Railway, Canadian National Railway, Kansas City Southern Railway, Norfolk Southern Railway, and Canadian Pacific Railway.
- Domestic firms, including non-Class I carriers, may have operations in foreign countries.
- Canadian and Mexican-owned railroads have a significant presence in the US. Both countries operate railroads in the US with enough revenue to qualify for Class I classification.
- The industry includes Amtrak, a federally-chartered company that provides national passenger rail services. Amtrak receives financial support from the federal government and fifteen state governments.
