Between the modes used to transport goods and commodities across North America, none are as cost-effective over long distances than rail shipping. And when shipping by rail, it’s almost certain that one of the major Class One railroads will be used.
Class One railroads account for the lion’s share of rail freight volume and play an essential role in connecting industries, powering economies, and enabling the seamless flow of goods to markets. With their expansive networks and massive capacity, Class I railroads offer scalable solutions that meet the demands of modern supply chains.
In this article we’ll take a closer look at Class One Railroads, starting with their earliest beginnings, then exploring how they came to be the carriers of today. After that we’ll examine their status, as well as some of the advancements the carriers are working towards.
The Origins of Class One Railroads
Early Beginnings and Infrastructure
The story of North America’s railroads begins in the early 19th century. The first rail lines laid in the 1820s and 1830s connected urban centers and industrial hubs, introducing a faster, more reliable alternative to horse-drawn carriages and canal systems. Railroads revolutionized commerce by reducing transit times and making long-distance transport possible for heavy goods. With railroads, businesses could scale operations and access new markets, creating a more interconnected economy.
Class One Railroads’ Growth and Expansion
The mid-to-late 19th century brought explosive growth to the rail industry. By the 1860s, North America had entered a “golden age” of rail expansion, driven by rapid industrialization and westward migration. The completion of massive projects like the Transcontinental Railroad in 1869 symbolized the connection of distant regions, allowing goods and materials to flow seamlessly between the coasts. This fueled nationwide economic development.
Railroads became a competitive industry, leading to the rapid creation of smaller lines, regional carriers, and private ventures. However, this fragmented landscape also began to become inefficient. As a result, a wave of consolidation came about by the late 19th and early 20th centuries. Companies merged and grew, forming the foundation of today’s massive Class One Railroads. This era saw the emergence of iconic rail carriers whose legacy continues to dominate the freight market.
Today’s Class One railroads are built on this legacy of growth and innovation.
The Transformation into Class One Railroads
Defining Class One
A Class One railroad is defined by the Surface Transportation Board (STB) based on annual operating revenue. According to the American Short Line and Regional Railroad Association (ASLRRA) in 2024, this was set at $1 billion or more.
A less specific definition is that Class One railroads are carriers that operate at a level that dwarfs regional and shortline carriers, often defined as Class Two and Class Three railroads. Class One railroads are the industry giants, commanding extensive rail networks that span large territories across Canada, the United States, and Mexico. They have billions of dollars in assets, thousands of miles of track, and the capability to move goods over vast distances without ever leaving their network.
Regulatory Landscape
The transformation of the rail industry into the system of today was shaped by a series of regulations, and later reforms. Early on, the federal government introduced regulations to the rapidly expanding industry, such as the Interstate Commerce Act of 1887.
However, by the mid-20th century, the industry faced declining market share as it struggled to keep pace with the flexibility offered by trucking and other modes. The Staggers Rail Act of 1980 was passed in answer to these challenges. By deregulating key aspects of rail operations, this legislation allowed railroads to adjust pricing, streamline services, and consolidate where necessary.
Today’s Class One railroads operate within a regulatory framework that prioritizes performance, safety, and sustainability. These giants have invested in advanced technologies and infrastructure upgrades to keep freight moving efficiently.
Modern Day Class One Railroads
Current Carriers and Market Presence
The modern Class One railroads dominate North America’s freight rail landscape. Currently, there are six major Class One railroads:
- Union Pacific (UP): Spanning the western United States, Union Pacific is a leader in intermodal transportation, connecting key domestic markets while playing a vital role in U.S.-Mexico trade.
- BNSF Railway: One of the largest freight networks in North America, BNSF excels in moving intermodal containers and bulk commodities, making it essential for industries ranging from agriculture to manufacturing.
- CSX: Operating across the eastern U.S., CSX specializes in integrating intermodal solutions with an extensive rail network that connects ports, warehouses, and inland hubs.
- Norfolk Southern (NS): Focused on the eastern U.S., Norfolk Southern leads in automotive and intermodal transportation, with strong ties to the U.S. Southeast’s growing industrial base.
- Canadian National (CN): Running from coast to coast in Canada and deep into the U.S., CN is a critical player in global trade, linking North American businesses with international markets.
- Canadian Pacific Kansas City (CPKC): Following its recent merger, CPKC boasts an expansive network that seamlessly connects Canada, the U.S., and Mexico, unlocking cross-border trade opportunities.
- Kansas City Southern (KCS): A key connection between the U.S. and Mexico, KCS merged with the CP to form the CPKC.
State of Class One Railroads’ Freight Logistics
Class One railroads are reshaping the freight logistics landscape through innovation and operational precision, creating more seamless, sustainable, and efficient supply chains for businesses seeking to optimize their shipping strategies. By leveraging advancements in technology, these railroads directly support shippers striving to balance cost, reliability, and environmental impact.
Intermodal transportation has emerged as a single, streamlined solution rail, truck, and ocean shipping. Class One railroads have placed emphasis on intermodal efficiency, building networks that ensure quick transitions between modes while minimizing delays and costs.
Railroads are also setting new standards for environmental stewardship with technologies that help reduce greenhouse gas emissions by up to 75% compared to trucking. Fuel-efficient locomotives, low-emission engines, and electrification initiatives enable shippers to meet sustainability targets by shipping on rail. Regenerative braking systems deploy additional energy-saving measures, capturing and reusing power while reducing fuel consumption.
Through Precision Scheduled Railroading (PSR), Class One railroads optimize rail movement. New innovations in safety and efficiency, such as electronically controlled pneumatic (ECP) brakes, enhance fuel optimization, train stability, and energy use while reducing stopping distances. Automation, including remote monitoring and semi-automated locomotives, further drives safety and operational productivity across the industry.
Modern railroads have redefined connectivity on a global scale, integrating ports, warehouses, and industrial hubs into interconnected networks that reach diverse markets and industries. From agriculture to manufacturing and energy, Class One railroads offer tailored solutions to meet unique shipping specifications.
