Geometry
| Radius | mm | Curve | Angle |
|---|---|---|---|
| R1 | 371 | R604 | 22.5° |
| R2 | 438 | R606 | 22.5° |
| R3 | 505 | R608 | 22.5° |
| R4 | 571.5 | R8261 | 22.5° |
| R5 (groot, bij Y-wissel/express-wissel) | 852 | R628 | 11.25° |
Power: 2-rail DC. Roadbed width 29 mm. Parallel spacing 66.68 / 32.74 mm.
Turnout pattern: R8072 / R8073 with counter curve R606; compensation R600.
9 combinations are recalculated on every build: circles that close, turnouts that land on the parallel spacing.
