advice on crossing/diamond

[streettrains]

I want to include a diamond on my layout, with to working turnouts, any adivce.. what would be the size of it...

Let's see if I can help you here. You want a crossing with 2 working turnouts? If that is correct, do the turnouts connect to each other by their diverging routes to form a curve? If that is the case, the turnouts will need to be far enough apart to run your largest engines and longest cars to look realistic. If the turnouts are #6's you will need at least (I'm guessing here) 2 square feet to put this together. Since I don't have anything like this I can only picture it in my mind. Someone with experience in this matter will have a lot more information on the space required.
I forgot to ask if this is for HO or N. I work in HO, so that's what I gave you for information. Hope this helps you some.
