An open wagon is a type of freight car that does not have a roof or sides, leaving the cargo exposed to the open air. It is used to transport bulk goods such as coal, gravel, or steel beams, as well as large or irregularly shaped items that do not need to be protected from the weather. Open wagons are commonly used for transporting goods that are easy to load and unload and are less affected by exposure to the elements.
