The minimal standards in T-Trak permit the flexibility to build modules of all shapes and sizes; however,
there are some basic modules that are essential building blocks in any layout. T-Trak modules fall into three main
categories: straight, corners, and junctions.
Corners, 180s, and inside corners. 282mm & 315mm radius
Junctions? .
Electrical - BWWB, feeder tracks, Kato terminal joiners, soldered wire & joiner connection.
Module construction techniques - box, inverted box, plank/foam, open frame, etc. Refer to links.
