What is the frog # for an Atlas "Y"?

Anyone have at their finger tips the frog # equivalent for an Atlas Y-switch, N-scale code 80 to be exact?

This is one I feel I know but can’t locate/remember.

Thanks for your help.

I can’t provide a direct answer but I believe that the Y frog number is simply doubled to determine an “equivalent” frog for a standard turnout. IOW A #4 wye is similar to a #8 TO in angle.

Can you just search the web for one? It might tell you there. I’m sure that someone will provide a better answer.

You are correct.

I don’t have an Atls N scale Code 80 wye at hand any longer, but I believe that I recall that the last one I looked at was about a 3.5+ nominal frog, or the equivalent of about a #7+ straight turnout.

The CAD progams on my PC suggest similar values, but it’s better to measure from the real thing if you have a critical spot in your track plan.
