Bringing the finest Model Railroad Ballast from real Rock

Our Founder, Philip Anderson, went to a hobby shop, and there weren’t any natural-looking model railroad scenery products for a layout project. I went around the countryside and sifted different sizes of sand and gravel. He started to find new gravel pits of different colors that can be used for various railroads. He brought a layout to a great American train show in Phoenix, and people asked where he bought my model railroad ballast. Arizona Rock & Mineral Company founded, and sales took off like gangbusters. We try to find a rock for all model railroads and locations. We only make model railroad ballast from real rock and doesn’t move as much when being applied compared to others. We try to make the application easy and a natural look.
