Technical Details

These links describe technical details of various aspects of the portable railway project. They vary in content from mathematical theory to construction details.

Transition Curves
This section is a description of the mathematics of Euler Spirals. The mathematical theory is implemented as numerical integration in computer code, which enables modules to host curves that transition to and from straight track to constant curved track.

Interfaces
Description and specification drawings of the railway interfaces.

Dual Gauge Junctions
Reliable dual gauge junctions can be somewhat tricky. This section describes how the portable railway junctions are designed and constructed.

Damage and Repair
One module was run over by an SUV; it survived and was repaired.

Miscellaneous Notes
Small but important points of interest.
