Look in craig's list and yur paper for people selling already busted stuff, hey as long as it rolls, have fun. I was at a train show Sunday, there's still guys selling beat up cars for a buck, I'll tell ya, the eventual repairing of this stuff is the point where you and your son leave toy trains, and enter model railroading. I still have a use, even if it is just part of the scenery, for cars I broke 40 years ago...
