As the turnout is 24.3 degrees, then geometrically speaking you should be using the 24206 (5.7 degrees) not 24207 (7.5 degrees)

But that is not your real issue if you wish to maintain 77.5mm spacing to the upper right.

Assuming the goal is ALSO to achieve a 30 degree delta WITH parallelism and alignment ...
The following is ONE possible solution ...

NOTE: If space (to the upper right) is not an issue and you wish to make the small kinks less noticable, you could retain ..
- the 172/188 instead of the 94/77
- and also use 229/236 for the offset instead of the 64/71 or 71/77

OR

From there you can "freelance/what-if" to get a bit more elegance

Hi Tim,
The turnout is actually 24.3 degrees of curvature. So yes it will work perfectly with the 24306 (5.7 degrees).

Regards,
Roger
