The dreaded minimum dia/rad curve question.
So I am beginning to think that next year I might start the expansion of the CR&N with the Fn2/O gauge run to another part of my yard. I want to run 32mm track for two reasons. I like the idea of a Fn2/fn3 dual gauge interchange. I also have acquired a couple of Steve Feather Kyle’s O collection that I would like to convert RC/battery and run on a dog bone. Steve’s O trains are the main driving force for the 32mm track. But the buildings and everything else will be set up as 1:20.3 (1:24) to match the existing layout.
With that said The locos I acquired from Steve’s wife are a FA and FB and then some passenger cars which are not extraordinarily long. I am not concerned with what “looks” right as far as overhang for the O gauge. I am more concerned with what it will reliably handle. I am seeing both 60" and 72" diameters coming up online. Is this fair? Can i really do 60" and get away with it because that would be awesome. I know many of the “toy” trains and Lionel starter sets came with much smaller diameter curves. So I am really hoping I can get away with 60" diameter. I think that would be plenty small enough.
