Freight carriages are specialized railway vehicles designed to transport goods and materials. Unlike passenger trains, these carriages are built to carry heavy loads, such as containers, bulk materials, or automobiles. They come in various types, including flatcars, boxcars, and tank cars, each suited for specific cargo needs. These carriages are an essential part of the rail freight system, which plays a crucial role in global trade. By using freight carriages, companies can efficiently move large quantities of products over long distances, reducing transportation costs and minimizing road congestion.
