Boxcar

A boxcar (the North American term; other terms include "goods van" (UK), "louvre van" (Australia), "covered wagon" (UIC and UK) or just "van" (UIC and UK)) 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.
