What are NTRAK Modules? 

NTRAK Modules are tables that "C" clamp together to form large N scale train layouts at conventions, shopping malls, club rooms, and as home layouts. The basic module is two feet wide, four feet long, and 40" high. There are adjustment bolts in the legs with a two inch adjustment range. The three tracks are common to all modules and the same electrical connectors are used on all modules. This makes setting up layouts a quick job. There are optional sizes and track locations to give a great deal of flexibility to the system. Specifications for the modules are covered in detail in the NTRAK Module Manual and in the The NTRAK Module 'How-to' Book. The 'How-to Book" is available in Kindle edition from Amazon and in print format from the Store.


There are a number of N scale modular standards.  A list and description of the major standards can be found here.

The NTRAK Standards section is where you will find the latest information on NTRAK standards including the updated 2 page summary, the download link to the complete standards manual and appropriate notices. Supplementary material is available for download, purchase through the store or in Kindle format from Amazon.   In addition, standards documents are available in German and Italian. All available material is listed on the Publications page.
