Our 15 piece resin Coal Yard Kit contains all the parts needed to build a scale house or office, a weigh platform and three coal bunkers. The kit includes a bunker layout plan and detailed assembly instructions so that you can create the design of our sample diorama shown here. The bunker walls can be arranged in a radial or a straight line. Roofing materials and tips are included for creating roll roofing on the office building. The coal piles, conveyors and unloader are NOT included.
