N Scale How much room - length, width would I need to install a wye? (The layout is 3 1/2 X 6).
Thanks.

That's going to depend on your locomotive types and how tight a radius they can go around without derailing.
Rough guess.
Assuming that the "base leg" is straight, the base will be twice the radius of the wye legs plus the length of two switches and the tail will go back the radius of the legs plus about 6 inches for the switch and however long you wan tthe tail track.
Assume 6 inch long switches, 11" radius and a 8" tail. That would make it roughly 32" wide and 25" deep.

Why don't you just download/print an N scale wye and place it on your layout. I believe FastTrack had some on their web site.

How long a train do you want to turn. ?
What radius track are you using for your layout?
If you use 15" radius track, the diameter of your circle is 30": Ergo, the distance between you main line turn outs is 30".
The tail is as long as the longest beast, consist or train that you are turning. If you are turning passenger cars, you will need room the the car and the locomotive.

The smallest wyes are made with three wye turnouts and have concave curved legs. Using 11" radius the wye proper should take about 17.6". Then you need to add the tail tracks say 5" each. But a stub leg of such a wye can be put directly into a corner saving a lot of space.
