My dad just pulled the old D-63 highway out of the attic. Unfortunately I didn't take any pictures of it. I will at some point over the holidays though since we are going to bring it over to my house soon. That way everyone will see how it works. It's actually quite simple. It's just a chain that has very long pins on between some of the links. Those pins stick up through a slot out of the face of the roadway. The cars are from Renwal. They are hollow shells. They just sit over the pins and the pins push the cars around. It's very low tech.
Our painted backdrop is broken in half and will require a degree of restoration at the split to make it look good again.
