Welcome to The National T-TRAK Layout
ATTENTION!!!
IMPORTANT NEWS!
The Chattanooga 2026 National T-TRAK Layout is officially FULL!
We are still accepting participant forms for participants without modules, but our module capacity has now reached its MAXIMUM capacity.


It’s happening! Our sights are set to break the current
T-TRAK layout record at the 2026 NMRA’s National Train Show at their National Convention in Chattanooga,Tennessee. (August 1 & August 2, 2026)
We are less than 6 months away fron this historic event!
With the support and sponsorship of ScaleTrains, we’ll be hosting an Awards Breakfast Banquet (for participants, their significant others, NMRA Conventioneers, and other interested N scalers) as well as conducting raffles, giving away prizes and lots of other free giveaways for all of our participants!
Participation in the layout is free and you do not have to be an NMRA member, nor do you have to be registered for the Scenic City Express National Convention, to participate in the layout. (Although we'd love it if you are!!!) and even though the layout is now full you can still participate without a module; we need extra help to man the reception tables, help set up the layout, operate trains, and engage the public! Participation requires being at the Convention Center on Thursday, July 30th to check in your modules and assist with setup.
Participants must also remain in Chattanooga, at the layout until the National Train Show is officially over, 4pm, Sunday August 2nd.
Fill out, complete, and submit this online registration form (button below) so you can be included and take part in this sure-to-be-memorable record breaking event!

The National T-TRAK Layout, at the NMRA's Scenic City Express National Convention's National Train Show (August 1 & 2, 2026) in Chattanooga, TN, will set a new world record for T-TRAK Layouts, breaking the previous record set in Kansas City, MO at the NMRA's National Train Show in 2018.
The Chattanooga layout will encompass 10,000 sq ft, consist of 880 individual modules of various sizes, or 1,704 equivalent single modules!
So far, participants from 35 different states are arriving in Chattanooga this August to make this record-breaking layout a reality!
We're proud to have ScaleTrains as the sponsor for our Sunday Awards Breakfast Banquet and the Best in Show T-TRAK module contest.
