In a perfect world all the modules would fit together exactly the same. However, we know that’s not the case. At Osborn Model Kits, we believe we have designed a product that sets the standard for all T-TRAK modules. T-TRAK is one of the fastest growing modular designs in recent years. Our modules are easy to build because of the interlocking construction and can be built up in very little time. The quality Birch plywood is laser cut for an accurate fit. Two unique features with our kits is the method of mounting the suggested Kato track (sold separately) to the surface and a jig to use to accurately position the track on the table. All these things come together to create a module that will be consistent every time. Other manufactures track can be used on this module as well. Using the conventional cork, track and ballast method you can still achieve a stunning result. The supplied jig can still be used to position the track. Keep in mind a portion of the Kato track needs to be used in order to snap the modules together.
