About This Report
This NAICS 482111 industry report integrates data from the U.S. Census Bureau[2] transportation surveys, Bureau of Labor Statistics[3] employment and wage statistics for railroad workers, and Small Business Administration[4] size standard tables. Fair Market Value researchers supplement these federal sources with Surface Transportation Board carload reporting data and Association of American Railroads industry statistics to produce quarterly updates. Each NAICS 482111 report revision captures freight volumes, employment trends, and competitive dynamics across the line-haul railroad sector.

Industry Definition & Overview
Line-Haul Railroads (NAICS 482111) encompasses establishments known as line-haul railroads primarily engaged in operating railroads for the transport of passengers and cargo over long distances within a rail network. These operations provide intercity movement of trains between terminals and stations on main and branch lines. Class I railroads including BNSF Railway, Union Pacific, CSX Transportation, and Norfolk Southern dominate the freight segment, while Amtrak operates the national passenger rail network under federal authorization.
The U.S. Census Bureau[2] separates line-haul railroads from short line and regional railroads (482112) that provide local freight service, and from support activities for rail transportation (488210) that handle switching and terminal operations. Freight rail moves bulk commodities including coal, grain, chemicals, forest products, intermodal containers, and automotive vehicles across transcontinental distances. Intermodal service combining truck trailers or containers on rail flatcars has grown as a core business segment, driven by cost and fuel efficiency advantages over long-haul trucking.
Rail infrastructure requires massive capital investment in track, bridges, signaling systems, locomotives, and rolling stock. Class I railroads spend billions annually on maintenance and capacity projects funded primarily through operating cash flows. Precision scheduled railroading principles have reshaped operating practices at several major carriers, emphasizing train length, asset velocity, and operating ratio discipline. Labor relations with multiple craft unions shape workforce management, and federal regulation by the Surface Transportation Board governs rates, service standards, and competitive access provisions across the industry.

Frequently Asked Questions
Common questions about this industry.
What businesses are classified under NAICS 482111?
NAICS 482111 covers Class I freight railroads, intercity passenger rail operators, and other long-distance line-haul railroad companies providing mainline freight and passenger service. The U.S. Census Bureau[2] provides the official classification.
How is NAICS 482111 different from short line railroads?
Line-haul railroads (482111) operate long-distance mainline networks for intercity freight and passenger movement, while short line railroads (482112) provide local and regional service. The Census Bureau[8] distinguishes them by the scope and distance of rail operations.
What is the SBA size standard for railroads?
The SBA sets the size standard at 1,500 employees for NAICS 482111. Class I railroads exceed this threshold, but smaller line-haul operators may qualify. Current standards appear in the SBA table of size standards[4].
Which NAICS codes relate most closely to 482111?
Key related codes include 482112 for short line railroads, 488210 for rail support services, 484110 for general freight trucking, 484121 for long-distance trucking, and 336510 for rolling stock manufacturing. Each interacts with the line-haul rail network.
What industries interact with line-haul railroads?
Short line railroads (482112) feed mainline traffic, trucking companies (484110, 484121) compete for freight, rail support services (488210) handle switching, and rolling stock manufacturers (336510) supply equipment. Shippers across agriculture, energy, and manufacturing sectors generate the cargo that line-haul railroads transport.
What activities does NAICS 482111 include?
Activities cover operating long-distance freight trains, intermodal service, passenger rail, unit trains, manifest service, and maintaining mainline track and infrastructure. The Census definition[2] covers the full scope of line-haul railroad operations.
Can smaller railroad companies get SBA loans?
Line-haul railroads with fewer than 1,500 employees qualify for SBA 7(a) loans covering equipment and working capital. The 504 program funds track and terminal investments. Details are at the SBA funding programs page[9].
Where are line-haul railroad operations concentrated?
Line-haul rail networks span the continental United States, with major corridors connecting Chicago, Los Angeles, New York, Houston, and Atlanta. Coal traffic concentrates in Wyoming, Appalachia, and the Midwest, while intermodal traffic flows between West Coast ports and inland distribution hubs. Agricultural rail traffic centers in the Great Plains and Mississippi Valley regions.
