Freight trains are specialized trains designed to transport goods and materials over long distances. Unlike passenger trains, which carry people, freight trains haul cargo such as containers, automobiles, and raw materials. They are typically longer and heavier, allowing them to move large quantities of freight efficiently. These trains run on railroads and are powered by locomotives that can pull multiple cars at once. Freight trains are essential for the economy, as they connect manufacturers, distributors, and retailers, facilitating the movement of products across regions and countries.
