R3/R4 Curved Turnouts.
The R3/R4 curved turnout was developed with the same idea in mind as the R1/R2 curved turnout, the only exceptions being that the former are laid out for the R3 and R4 radii with a curve angle of 30°. The track arrangement is hence considerably wider in radius. Despite that the space requirement is not all that great even for smaller layouts.
Curved Turnouts For Radii 3 and 4. The turnout branch is 30°. Optional Stop Turnout function included. An electric mechanism can be installed on these turnouts.
