A freight train is a type of train that carries goods instead of passengers. These trains are made up of several cars, each designed to transport different types of cargo, such as containers, coal, or automobiles. Freight trains are essential for moving large quantities of products over long distances, making them a vital part of the transportation system. Freight trains are typically longer and heavier than passenger trains, allowing them to haul significant loads efficiently. They travel on railroads and can connect various regions, helping businesses receive the materials they need. This efficient mode of transport plays a crucial role in the economy by facilitating trade and commerce.
