Subject line says it all… what are the radii of peco turnouts -small medium and large. Also, are they continuous radius through curved leg?
Each one is different. I don’t know what they are in radius, but they all curve out at a 12 degree angle so 4 of them can be married up to a Peco 24 degree crossover to form a double-crossover.
You can see actual pictures of each at http://www.cchobbies.com or check the Peco website, where they might indicate their radius.
I’ve a bunch of medium turnouts they about a #6 equivilent. The curved leg isn’t a continuous radius.
Ken.
It helps to know what scale you’re asking about – N or HO.
mmm Code 100 kinda gives it away?
The PECO HO C100 turnouts are curved through the diverging leg, which is one of the reasons they are viewed by some as less accurate in appearance for US trackwork.
All have the same frog angle, nominally a #6. So it is more accurate to define them by the radius of the diverging leg.
Small 24"
Medium 36"
Large 60"
Curved 30"/60"
Small Radius Wye 24"
Large Radius Wye 72"
This information is available at a number of places on the net (but not at PECO’s site!). One of them is the Loy’s Toys site:

This isn’t necessarily a recommendation to purchase from Loy’s, but kudos to them for taking the time and effort to offer the information.

Peco curved turnouts are in the following sizes:
Small curved turnout: 18/22 inch radius
Large curved turnout: 30/60 inch radius
Does anyone have the same information for Peco’s line of “Setrack” turnouts? They appear sharper than even the Peco small-radius turnouts.
Again, from the Loy’s Toys site:
http://www.loystoys.com/peco/100-if-turnouts.html
The set-track tunrouts are listed as “tiny radius” and are at the bottom of the page. Diverging radius is 17.25". The loy’s site indicates that the frog measures to about a #3.

Outstanding! Thanks…fortunately 17.25" is fairly broad curves for my layout!
thanks everyone for the info.
