Rail transport in the United States consists primarily of an extensive freight rail network, with a significant but secondary passenger system. The United States has the largest rail transport system in the world by total operating base length, with freight railroads moving a substantial portion of the nation's industrial and agricultural goods. While passenger rail service is dominated by the federally chartered Amtrak, it plays a more limited role compared to other modes of transport like automobiles and aviation.
The first common carrier railroad was the Baltimore and Ohio Railroad, chartered in 1827, which began a rapid expansion of rail lines across the Eastern United States. The completion of the First transcontinental railroad in 1869, built by the Central Pacific Railroad and the Union Pacific Railroad, was a pivotal event connecting the Atlantic and Pacific coasts. The late 19th century, known as the Gilded Age, saw intense competition and consolidation among powerful industrialists like Cornelius Vanderbilt and Jay Gould, leading to the creation of massive systems. Following World War II, the rise of the Interstate Highway System and commercial aviation led to a steep decline in passenger rail, prompting the creation of Amtrak in 1971. The Staggers Rail Act of 1980 dramatically deregulated the freight industry, leading to the modern, highly efficient private freight network.
The U.S. freight rail network spans approximately 140,000 miles, primarily owned and operated by private Class I railroads. Major corridors include the Union Pacific Railroad's route over the Donner Pass and BNSF Railway's Transcon line between Chicago and Los Angeles. Key infrastructure features include major classification yards like Bailey Yard in North Platte, Nebraska, and critical tunnels such as the Cascade Tunnel in Washington. The network uses standard gauge and is heavily reliant on advanced technologies like Positive train control for safety. Passenger rail infrastructure is largely shared with freight operations, with notable dedicated segments for Amtrak's Northeast Corridor.
Freight railroads in the U.S. operate on a precision scheduled railroading model, focusing on high-volume unit trains. They dominate the transport of bulk commodities, moving the majority of the nation's coal, grain, and chemical shipments. Major traffic flows include Powder River Basin coal to utilities across the Midwest and South, and intermodal freight transport containers from West Coast ports like the Port of Los Angeles to inland hubs such as Chicago. The Association of American Railroads reports that railroads handle over 40% of long-distance freight ton-miles, more than any other single mode.
The freight sector is dominated by seven Class I railroads, which include western giants Union Pacific Railroad and BNSF Railway, and eastern systems CSX Transportation and Norfolk Southern Railway. Other significant Class I carriers are Canadian National Railway and Canadian Pacific Kansas City, which have major U.S. operations. Regional and shortline railroads, such as the Iowa Interstate Railroad and Genesee & Wyoming, operate over 45% of the network's mileage. The primary passenger operator is the federally chartered Amtrak, while major metropolitan areas are served by public commuter rail agencies like Metra in Chicago and the Long Island Rail Road.
Intercity passenger service is primarily provided by Amtrak, which operates over 300 daily trains on a 21,400-mile network. Its busiest and only high-speed route is the Acela Express along the Northeast Corridor, connecting Boston, New York City, and Washington, D.C.. Long-distance routes, such as the California Zephyr and Empire Builder, provide national coverage but are less frequent. Major metropolitan areas are served by extensive commuter rail systems, including the Metropolitan Transportation Authority in New York City and Metrolink in Southern California. Several states, like California and Illinois, sponsor and fund additional corridor services.
The primary federal regulator is the Surface Transportation Board, which oversees economic regulation, and the Federal Railroad Administration, a division of the United States Department of Transportation, which enforces safety standards. Key safety legislation includes the Rail Safety Improvement Act of 2008, which mandated the implementation of Positive train control technology nationwide. Labor relations and collective bargaining are governed by the Railway Labor Act, administered by the National Mediation Board. Major industry advocacy and standard-setting groups include the Association of American Railroads and the American Short Line and Regional Railroad Association.
