Here we have a top-down view. Pretty simple insides. Those boxed-in areas at each end hold more weight. This little car (just over 4" long and 1.5" wide) will weigh almost 4.5 ounces when it is finished. Pretty simple construction, I know, but I'm going for a finished effect here, not a detailed freight car that is built board-by-board to match the framing of a real boxcar! That takes too much work. This is meant to be a two- or three-evening project, and I'm keeping construction as simple as possible.

That said, thoughts on what kind of roof to use? I've got five stock cars about the same size with corrugated metal roofs, so I'd like to avoid that...
