From the TrackDrawer Guide
- The tightest curve radius in N and what it means for your baseboard
- An N layout on 100 x 50 cm: what fits?
- Your layout will not close: a gap of a few millimetres
Geometry
| Radius | mm | Curve | Angle |
|---|---|---|---|
| R1 | 228 | ST-3 | 22.5° |
| R2 | 263.5 | ST-14 | 22.5° |
| R3 | 298.5 | ST-16 | 22.5° |
| R4 | 333.4 | ST-18 | 22.5° |
Power: 2-rail DC. Roadbed width 24 mm. Parallel spacing 34.7 mm.
Turnout pattern: ST-6 / ST-5 with counter curve ST-3; compensation ST-1.
6 combinations are recalculated on every build: circles that close, turnouts that land on the parallel spacing.
