A cargo train is a type of train specifically designed to transport goods and materials rather than passengers. These trains consist of a series of freight cars that can carry a variety of items, including containers, automobiles, and bulk materials like coal or grain. Cargo trains are an essential part of the logistics and supply chain, helping to move products efficiently over long distances. Cargo trains operate on a network of railroads and are powered by locomotives that pull the freight cars. They are often more economical and environmentally friendly compared to road transport, as they can carry large volumes of goods at once. This makes them a vital component of the global economy.
