@Chuck K posted:Another key for you will be radius. If you are going to run scale wheels, stay away from the 20" sectional track curves and 20" turnouts. You'll want the 27" or #5 turnouts offered from the above mentioned brands. And beware that even the 27" curves/turnouts do not accommodate large scale wheeled steam engines from the brass fine scale manufacturers like River Raisin.
Usually I run mainly vintage and modern diesels pulling freight cars, no steam and no passenger coaches. Probably I have to avoid narrow curves and tight turnouts. Thanks, Chuck, for the useful explanation about the recommended track geometry.
