Hello all would like to switch my scale 0 engines, freight & passenger cars to scale couplers, my minimum radius is 072. Which ones would you suggest for these. Thanx in advance for your help. Jim

Good question, I will be in the same boat soon. Nick
Using 72 radius, easily you can use body mount couples.
The 700 series look awesome and work flawless.

O-72 is a diameter, so you'd be operating on a 36" radius. That said, if you're using 18" MTH passenger cars, they should work on O-72 using Kadee couplers. Cars longer than that may have problems depending on configuration. What will complicate matters is that passenger cars have their trucks set back a little farther from the end sill of the car, so additional coupler swing is desirable. You might want to use the long-shank Kadee 700 series (#746) for passenger cars and the 740's on the locomotive(s) and head end express cars. The 800 series does not have a long-shank version.
If you're retaining the hi-rail wheels, you'll more than likely need shims to get the couplers to the right height.
Detail drawings from the another thread posted. There are more coupler offering than what is shown in this post.
From the Three Rail scale forum. Commonly used Kadee Couplers from the Kadee website. Note the 700 series and some of the advantages.
Helpful diagrams from the Kadee site. A lot of information on this page.
Added 745 and 746 diagrams. 4/3/13
