T-Trak is a modular layout standard for N scale railroads. I decided to go with it after researching shelf layouts and realizing that I would rather run my trains on a table than on a shelf over my head, and with these modules, I can still keep them on the shelf and out of the way when not in use. The modules are very small (about the size of a sheet of paper) so I shouldn't have any problem storing them up on shelves.
The small size presents a challenge in terms of scenery and layout, but I'm looking forward to coming up with new ideas to keep each module fresh and unique. Also building them one by one makes getting back into the hobby easier, breaking down the cost and time required into manageable chunks.
There are also two single-track variations that are compatible with T-Trak. The first is called T-1-Trak and is documented in The Unofficial T-TRAK Handbook. It follows the main standard almost exactly in terms of module size and the only difference is that a single mainline is used.
The other standard has been termed Mini-T and comes from Japan by way of Popoya 2008. These modules are full length, but only 150mm (6 in.) deep. They also feature a single track mainline.
This image represents my layout plans for the short term. All the standard and corner modules are built or in progress. The interchange and the yard are still in the planning stages.
