Ceiling Shelf Train HO Scale

This video was uploaded from an Android(Samsung Moment) phone. This is a train set I'm building for my boys. I now have all the trackbed laid for the first main line with siding. I should have the second main line with trestles to raise it up to the second level finished in a week or so. The train is made up of about 20 or so rolling stock being pulled by two powered locos. It would be about 1/3 mile long in real life.
