The Woodland Scenics(R) Subterrain(R) T-Trak Module Kit with Unitrack makes it easier than ever for modelers to get into scenery and layout building. Each SubTerrain T-Trak kit is made from lightweight, sculpt-able foam with wooden reinforcements that make them easy to assemble, transport, and shape into your desired form! Included in each set are a variety of sculpting aides, like a Woodland Shaper Sheet(R) and sculpting plaster, as well as all the tools you need to assemble the completed module kit - even glue! Kits for standard T-Trak straight and curved modules are available. Once you′ve built the kits you can connect them - they share a standard interface. Use several to build your own layout section by section or connect them to other T-Trak modules around the world!
