A Mogul with rigid drivers would probably do 36" radius, but the problem is always the lead truck and drawbar. Realism and tight radius are opposites.
Here’s a video that disproves that:

100% stock Glacier Park 2-8-0 traversing a 36” radius S curve with no straight track between the curves.
Tomorrow I’ll post a photo of what I call “jointed” main rods I’m probably not using the right terminology but don’t know the proper term
