I have a N 2-8-4 Berkshire Steam Locomotive with Tender. What is the smallest radius the this locomotive can handle without the tender derailing?
I've never had any problems running mine on 9.75" radius curves, although that's really pushing it. 11" is probably a more realistic minimum.

Thanks Mark!
I have an area on my Christmas layout that has a 20 degree section of about 8' radius that goes into a 9.5 radius turn the other direction. That transition blows the front truck of the tender right off the track. This gives me a real good reason to redesign my Christmas layout.
