This ad is for an HO scale nodel train set layout,trains, and accessortes. It is 4' x 8'. It is 3 years old but has only been used once. The layout has 3 loops of track so you can run 3 seperate trains. It also comes with a lot of extra track, and other accessories. The reason I am letting this go for such a great price is I just don't have room for it as I have a very small home. This really is a steal for someone who is a model train enthusiast.
