National T-TRAK World Record Layout Attempt!

The 2026 NMRA National Convention will be hosting the National T-TRAK layout in their attempt to set a world record on the largest T-TRAK layout, currently held by the 2018 National Train Show layout at 28.4 scale miles. We will have 10,000 square feet of space to assemble the largest layout we can – and we need your help to do it!

Head over to the National T-TRAK website at https://nationalt-traklayout.com/chattanooga-2026 and register your modules to be a part of this layout. There is plenty of time to build a module if you don’t already have one!
