I am building a 5 inch gauge railway in my garden, minimum radius curve is expected to be 15ft.

I am using the PNP system which allows gauge widening of 1/32 or 1/16 for tighter curves, but they don’t specify how tight.

How much gauge widening would you recommend for a 15ft curve.

I should just be running 0-4-0 locos.
