Build the layout of your dreams - one module at a time. Module Kits can be assembled and bolted together side-to-side in any configuration. The Straight Module Kit creates a module base and scenic board that is 18" deep x 36" wide. Woodland Scenics supply a wide range of scenic materials, making this much more than a baseboard kit. Materials include track bed, ballast, adhesives, plaster roll, scenics scatters, loose rock materials and tree armatures with foliage material.
