T-TRAK on a Budget: Build It Yourself and Save
One of the biggest advantages of T-TRAK model railroading is that you don’t have to spend a fortune on the basic module. With a little time and some simple woodworking, 5 mm plywood can produce a lightweight, strong T-TRAK module for a fraction of the cost of a commercial kit.
For the Southern New Mexico N Scalers, we’re looking at using the standard T-TRAK widths for single, double, and triple modules, while using a 14-inch depth to provide more room for scenery and structures.
What Does the Plywood Cost?
Home Depot currently lists a 3/16-inch, 2’ × 4’ plywood project panel—the closest readily available size to 5 mm—for about $11.54 per sheet.
A 2’ × 4’ panel provides 8 square feet of material. Enough for 1 triple module!
With an efficient cutting plan, that inexpensive sheet can provide most or all of the plywood needed for a T-TRAK module.
Approximate Material Cost
Module: Single Double Triple
Width: 12-1/8” 24-1/4” 36-3/8”
Depth: 14” 14”. 14”
Approx.
Plywood
Cost*: $6-$12 $12-18 $12-$24
*Estimated plywood consumption depends on the module height, internal bracing, and cutting layout. Actual cost can be reduced further when multiple modules are cut together to minimize waste.
Add a few dollars for wood glue, brads or screws, and miscellaneous hardware, and a reasonable target for the basic scratch-built structure is roughly $10–$25 for a single and $20–$30 for a double or triple, depending on material efficiency.
Compare That With Buying a Kit
Commercial kits offer convenience, precision-cut parts, and instructions—but you’re paying for those services.
For example, current N-scale commercial T-TRAK single-module kits are selling for approximately $28–$30 before track and scenery.
That means a scratch-built module can potentially save $15 or more per module.
Build ten modules and the savings can easily reach $150 or more.
For a club building a large layout, that adds up quickly.
Where Should the Savings Go?
That’s the real advantage of scratch-building.
Instead of spending another $15–$20 on the box, that money can go toward the things people actually see:
- Kato Unitrack
- Ballast
- Structures
- Vehicles
- Trees and vegetation
- Figures
- Lighting
- Signs
- Scenery materials
In other words:
Build the benchwork. Buy the details.
More Than Just Saving Money
Scratch-building also gives us something a commercial kit can’t always provide: complete control over the design.
A 14-inch-deep module gives us substantially more scenic space than a traditional shallow module. We can build Southwestern scenes featuring desert washes, industries, highways, depots, ranches, mines, and small communities.
And because the module widths remain standardized, individual modules can still come together to form a much larger railroad.
The Bottom Line
Commercial T-TRAK kits are a great option for someone who wants convenience.
But if you’re willing to spend an afternoon cutting and gluing plywood, scratch-building can put considerably more railroad on the table for your dollar.
At roughly $11.54 for a 2’ × 4’ sheet of 3/16-inch plywood, the basic structure is inexpensive.
For a Southern New Mexico N Scalers club project, that makes scratch-built 5 mm plywood modules an attractive way to get more members involved, keep costs down, and put the savings into the part of the hobby we all enjoy most:
Building the railroad.
