Y turnouts

[MitchyG]

If there is a #3 Y turnout, would it actualy only have the turn of a #6 standard turnout?

I'm not sure what you're asking. In general, the diverging routes from a wye turnout are twice the radius of the turnout number, so a #3 wye would have diverging routes that have about the same radius as the diverging route of a # 6 switch.

That's right, UP...

I have some Shinohara #2 wyes that mate up with #4 turnouts...

Yes. I use a hand-laid #3 whose diverging routes do that at the same rate as a #6 through the frog and beyond. In fact, it actually continues to curve just a fraction, so it isn't strictly a N. American standard appliance. But, it works just dandy.

Thanks! that's exactly what I wanted to know.

 

[MitchyG]

knowing this, what would be equivalent to a 22" radius turn?

 

[UP2CSX]

Well, a #4 has about an 18" diverging route and a #6 has about a 24" diverging route. I think a 22" diverging route would be a #5. They aren't common, but you can find them, aprticularly in the Peco and Walthers/Shinohara lines. I know Atlas Customline had a #5 switch at one time, but I don't know if it's in production any longer.

Thanks!
