Minimum Curve Radius

Is there an easy way to determine or a posting to read that delineates the minimum curve radius that a particular locomotive or engine will tolerate? Same question goes for turnout size. Thanks!

***,

You’ll find a lot of discussion on this subject (and/or you’ll get answers) over on the Model Railroader forum.
The same goes for your painting question.

Good luck,

Mike in Philly.

Thanks Mike ,for the reply!
