Published S7 standards
In these pages you will find the basic standards, originally outlined at the formation of the ScaleSeven Group.
- Track and Wheel Standards — the basic design dimensions, from prototype dimensions to the 7mm scale equivalent. The main page deals with 4ft 8-1/2in standard gauge. Click here for Irish 5ft 3in, or here for Brunel 7ft 0-1/4in.
- Wheel and Rail Relationships — how the tyre profile relates to the rail.
- Working Dimensions and Tolerances — the standard dimensions a modeller can use to work to ScaleSeven standards.
- ScaleSeven Tyre Profile — dimensions to which a model tyre must be reprofiled to conform to the ScaleSeven standards.
