A boxcar (the American term; the British call this kin of car a "goods van" while in Australia, they are usually referred to as "louvre vans") is a railroad car that is enclosed and generally used to carry general freight. The boxcar, while not the simplest freight car design, is probably the most versatile, since it can carry most loads. Boxcars have side doors of varying size and operation, and some include end doors and adjustable bulkheads to load very large items.
