Here are the module design specs in PDF format.
- Basic Module The basic module is 47 1/4 by 30 inches.
- Small Radius Curves The small radius curve is 1/4 of a circle.
- Large Radius Curves The large radius curve is 30 degrees, or 1/12 of a circle.
- Transition Modules Transition modules shift the double track for when we
wish to use inside curves, set a bridge into the layout, or just for senic variation.
