Super Modules

4 x 3 ft
and 19" x 5 '


Installed, track transfered, and trains running.

I may reuse the old T-Trak modules for the HO Christmas train?

Module Re-Work

Chopped all 4 corners down to 2 3/4" + feet.

Pull the corners out.

I sawed them at the glue line (a bear) and then removed the 3/4 piece and glued them back to the plywood base.

Still a bit tall for the "std" but look much nicer lower.

Now I need to build the two new "super modules" and transfer the track from the existing modules.
Then I'm back on track (no pun intended)😉


My "goal" design has evolved to some form of finality but I am begining to recognize that the T-Trak modules are too small for a home layout.

Modified (hybrid) Approach

Incorporate the "siding" modules into a new large 36" deep module which will include a new South Loopback (with an industry or two), and also support a segment of the high route track.

High Route

Start the high route off the outside "mainline" in the Yard module and reconnect with the inside "mainline", after a double crossover in the "city", connecting on the "duck-under" "bridge".
Still some "magic happens here" for the supports of the high route corners.

Construction Milestone!

Milestone of progress with the construction phase

The "Duck-Under" bridge

Basic structure and functionality is there.
Need to level and position laterally (which will require some tweaking)

An Ebay addition - string of ore cars


The Yard Module

15" x 5'
Need to level the surface (somehow), the track work is designed, but purchse and actual install will be "later".


That polyiso foam is crap.
The covering doesn't remove well, it is not flat (many depressions across surface) and its expensive.


Removed the track and 2 switches from the siding modules. Scraped one module because my attempt to level the surface of the polyiso foam had made it much worse. The original modules, I think we sized wrong. They should be 310 mm. exactly the same as the ballast of the Kato straight + the 62 mm (1/4). One of the T-Trak sources had said 308 mm. I think that's wrong. But, cutting the 2" foam with the sharpened putty knife is not very "accurate" - very diffucult to be precise.


I believe the module constructon phase, and bench work, is complete! Thank gawd. My least favorite part.
Ordered enough track to finish the loop.
I think that's


operational Phase 3 Rev A

Bench work

4 1/2 height Gorilla racks with a "bridge"
The "bridge" is 4x2 ft 1/2" plywood set into aluminum angle "iron" pop riveted to the bench.
Gives some stability to the two benches, as well as supporting the 4 single modules.

More Modules, Yard

Glued up 2 more single modules.
Ordered legs. Still quite a few hurricane nuts, but used up the legs, already!
Cut and assembled Yard module 4' x 15"

T-Trak Module Approch

Build Initial T-Trak Modules (boxes)
Scraping the box approach in favor of the slab and foam approach!
