Hello Ian, welcome to Trainboard I have to say I was not aware of proto160 so cannot help with your query, but hopefully someone will be able to help. Do you have any more info on proto160, I assume there are a set of wheel and track standards, etc.?
Hi Ian! I'm not aware of anyone doing such fine scale modeling in N. But wouldn't be surprised to learn I'm wrong. The only Group I ever knew of, that proposed some ideas, was an N modular club in California. I have not checked to see if the URL is still good. Here it is: www.socaln.com/group160/ Good luck!

Haven't seen any, but always wished someone would sell photo-etched sheets of these to be added to C55/40 rail. I think it would be a nice way to spruce up N-scale track.
Must confess that is a new one on me, and I hang around a number of N scale forums. If you find out, enquiring minds want to know.
I tried a Google search. The only page with any mention that came up: http://www.scalefour.org/history/manual/P4Man20.htm Boxcab E50
