Coal carts are specialized vehicles designed to transport coal from mines to processing facilities or markets. They are typically made of sturdy materials to withstand the heavy weight of coal and often feature wheels for easy movement along tracks. These carts can be pulled by locomotives or horses, depending on the era and location of use. In the past, coal carts played a crucial role in the coal industry, especially during the Industrial Revolution when demand for coal surged. They helped streamline the transportation process, making it more efficient to deliver coal to power plants and factories, which were essential for fueling the growing economy and industrial activities.
