Homemade track cleaning car

I had a piece of plate steel laying on my workbench that just happened to be about the right size to make a standard gauge car, I also has a couple of trucks Some old decals and a piece of a vinyl trim board that I used to fix my front porch. I put them together and it makes a track cleaning car that actually works. The abrasive pad I stole from the kitchen sink and attached it with a rubber band. The only things i bought for this masterpiece? of home engineering were the couplers, screws and binding posts that the pad rides on.   I guess I was bored but it came out pretty good and it works!
