i don’t know why you think it won’t work. I have had curved TOs that did work. Just because someone says that it isn’t possible doesn’t mean that it isn’t. If you have to use a code 100 instead of an 83, simply shim the track.

Thanks, That was very good info.

I have a Walthers 948-8827 C83 #6.5 right-hand curved turnout on a 22" radius curve main line and it fits the curve perfectly. The diverging route is done with flextrack into track that runs parallel with the main line for a short distance before curving away in another direction. I’ve had no operating problems with the turnout. The turnout is actually a Shinohara product but Walthers sells it in their catalog under their name in their C83 product line.
Hmmm … I have those: they are labeled 24"/20" and measure 24"/18". I checked by laying out curves on a board at different radii, 2" apart. Their #7 measures 28"/22".
