? are there #8 special turnouts on the market?

[Steamtrains]

I suggest you take a look at Peco turnouts. They are well made and have a large radius turnout which is probably close to a #8. They also have double slips, 3-ways, and I believe crossovers as well. I've used their mediums (approx #6's) exclusively on my layout and are very satified with their performance. They are a bit on the pricey side, but it pays off in the long run. There's nothing like a smooth running layout....

A belated welcome to The-Gauge....
