Since 1947, hobbyists and collectors have made Plasticville U.S.A. products their structures of choice. Plasticville pieces add character and dimension to your HO scale layout. Many buildings and accessories have been added to the Plasticville line throughout its history, and many are still produced from their original molds. As a fun challenge to collectors (you can even join the Plasticville Collectors Association), you can collect hundreds of product, color, and packaging variations that have occurred over the years. City growth is limited only by your imagination.
