Has anyone considered doing a model of these? They are basically a square cast pipe under the track. They have a tapered apron, and angled wings to keep water from eroding the grade fill. I have seen them from about 3 feet (1M) square at the smallest, and in sizes up to large enough for a medium size truck to pass through. I am working on a short line in our area, and they use these in several places. Thanks, MM
