Shortline refers to a type of railroad company that operates on smaller, regional tracks, often connecting to larger Class I railroads. These companies typically serve local industries and communities, providing essential freight services that larger railroads may overlook. Shortlines play a crucial role in the transportation of goods, helping to support local economies. Shortline railroads can vary in size and scope, with some operating only a few miles of track while others may cover hundreds. They often focus on niche markets, transporting specific commodities like agricultural products, timber, or mining materials. By offering flexible and tailored services, shortlines contribute significantly to the overall freight network.
