What diameter curve does a #4 switch equate to?

It doesnt, the diverging leg of a numbered turnout is straight, and diverges at 14 degrees. You could probably email Steve at Ross switches and ask what the effective radius of the moving points/frog is, but its something quite large.
MikeMike you were talking Standard gauge on another thread. Back to back #4s will give track centers of 7.25 inches. The spacing between 42 57 72 and 87 curves is 7.25". There is a plan.

For O gauge a No. 4 switch will handle all trans that require O-72 curves.

Ross #4 switch will not handle a 3RD rail PRR I1s decapod in reverse. Ross #6 & O72 will. Ross #4 will handle PRR J1 in reverse.

I was wandering because of standard gauge. I am trying to find the width required to add another 072 loop on the std gauge plan. Ross says their 072 with transition piece will give 3.5 centers for the straights. I thought #4 may be less. Maybe it should just be an independent loop and forget about switching to it.
