I am struggling with some "old work", meaning I am making changes to existing structure. As a result there has to be some creativity. My plans are to install a scissor crossing, I have done one before but on "new work" when everything will fit nice.
I want to install a turnout on a curve, I have used the Peco curved turnouts before, but in this case it would work better if I used a Peco Small Radius Y Turnout (SL 97). The right portion of the Y would fit to an existing curve and provide one of the four turnouts that are part of a scissor crossing.
What are the implications? Is not the Y Turnout another form of a curved turnout? I run 1950's era and have only one steamer that has troubles on portions of my layout.
It is not a curved turnout because the divergent tracks are not curved. But the Y turnout may accomplish what you are trying to do.

You do not present your track plan, but yes, there are indeed times when a Y turnout is strategically approprite and useful. Whether the small Peco Y is best I leave to you. Assuming one leg of the Wye turnout is part of a regular curve, the one issue I can think of is, would the "diverging route" off the Y create a bad S curve situation that would be an invitation to problems?

Actually, the PECO Code 100 Streamline wye the original poster mentioned does have curved diverging legs, but you're right, it's not what most would call a curved turnout. As others have mentioned, adding this part to a curve would create potentially unreliable S-curves.
[PECO Code 83 wyes, in contrast, have straight diverging legs.]
