For many people, the trusty boxcar is the image that comes to mind when they think of freight trains. The boxcar is a highly versatile railcar. It can carry packaged freight, whether it's bagged, boxed, crated or attached to pallets. Boxcars may look simple at first, but they come in many configurations. Unlike intermodal trains that go from hub to hub, a train made up of boxcars goes to the source. It will pull right up to a manufacturing facility's loading dock.
