T-Trak: Module building to a higher standard

Kato and Woodland® have teamed up with a brand new project to make it easier than ever for modelers to get into scenery and layout building, thanks to T-Trak(TM) and UNITRAK!

Kato USA will be distributing special T-Trak module kits, made by Woodland using their SubTerrain Lightweight Layout System®! 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® and sculpting plaster, as well as all the tools you need to assemble the completed module kit – even glue, and of course, Kato UNITRACK!

Learn more about the T-Trak module system of standards here: www.ttrak.org

Modules are available in “Straight” and “Corner” variations, and are designed to T-Trak standards to allow multiple modules to “snap” together using the power of Kato’s Uni-Joiners. Thanks to the standardized dimensions, these kits can be connected to any existing of future T-Trak modules, whether they’re built using these kits or not!

Pictured to the left is a sample of a Straight T-Trak module, with some sections already carved out using a hot-wire cutter. One of the big advantages of using the SubTerrain foam system is that it allows building not scenery not only above but also below the level of the track - a difficult venture using an all-wood structure.

Shown here is the final product - with a hill area built upward using Woodland's Shaper Sheet and a river section carved out below. This type of module can be easily built by modelers of any skill level thanks to the easily worked materials! By combining easy to assemble and sculpt terrain tools with the reliability of Kato UNITRACK, Kato and Woodland have made a modular kit system that can be enjoyed by anyone, whether it's during the building, painting, and decorating process, or during operation when combining multiple modules into a decorated layout!
