Although they are one of the lightest loads carried by rail, they require one of the biggest cars! Wood chips are big business for today's saw mills and lumber operations. Once burned as scrap or fuel-on-site, these by-products of the lumber industry are purchased by paper companies and used to make paper. Walthers' all-new Woodchip Hoppers are faithful reproductions of cars now in service with several roads. It's easy to build a fleet because they come fully assembled, prepainted and lettered and ready for service on your railroad.
