Class I railroad

A Class I railroad is a major freight railroad company that operates extensive rail networks covering large regions, often across multiple states or countries. They handle the transportation of large volumes of goods, such as raw materials, manufactured products, and commodities, primarily for industrial and commercial purposes. These railroads are characterized by high revenue thresholds set by regulatory agencies, and they typically own and manage thousands of miles of track, large fleets of locomotives, and extensive infrastructure to support national and international freight movement efficiently.
