The Spectrum Baldwin 2-8-0 will easily handle 18 inch radius, the IHC 2-6-0 mogul and I think most 2-8-2 mikado's will handle 18 inch ok. I think most 4-6-2 Pacific types will also handle 18 inch radius. For slightly bigger power units the Mantua articulated 2-6-6-2 loggers should handle 18 inch radius.
