Underground Mine Train

A dark, rugged underground cavern features a line of grey mine carts, each heavily loaded with black coal. The cavern's ceiling is marked by large, dripping formations in shades of orange and yellow, resembling molten rock or glowing stalactites, contrasting with the dark brown, jagged ground below. The scene depicts an industrial operation deep within the earth, transporting valuable resources.
