Joined: 28/08/2025(UTC) Posts: 9 Location: Lombardia, Milan		hello I'm trying to design a 3 tracks parallel curve to fit my layout into may garage. the reason why I want to stick with 24230 and not go to 24130 is to make sure that steam loco will be able to run. the problem I face is that by using rail modeler I can't find a good option to design it. has some of you already gone through the same issue and has any suggestions? thanks

You could use a mix of R2 and R3 (24230 and 24330) to reduce the number of 24077 track pieces. R4 was made for a track spacing of 64 mm, but result may look better with a mix of R2, R3, and R4.

I can't make it even on the straights :-( Screenshot 2025-10-22 alle 14.21.39.png (1,062kb) downloaded 8 time(s).

Note that the 24611 and 24612 switches are just there to establish the 77.5mm separation between tracks. Also, what steam locos are not able to handle the 24130 radius??
