does any manufacturer make a curved turnout with the outside curve close to 15" radius?

Wow, I doubt it, since that's going to brutal on your HO rolling stock not only on the outer curve but also on the even sharper inside curve.  However, you could have someone custom build one for you, if you are unable to build your own turnouts.

I don't model in HO, but, for comparison purposes, I have an N scale curved turnout that Chris333 built to my specs: 10" radius outer curve and 8-1/2" radius inner curve.  If I'm doing my math correctly, that would be the equivalent of approximately an 18-3/8" outer radius and a 15-5/8" inner radius in HO.  It's tight, but, thanks to Chris' fantastic handlaid track work skills, it works well.  I'm not sure I'd want to go much sharper, though.



Hope this helps,

Best I can come up is the Peco Set Track Curved points, slightly larger than what you wanted at  17 1/4" outside,14 5/8" inner.

Central Valley makes flexible tie strips for turnouts, but you have to lay your own rail.  I don't know if any of their frog sizes will flex down to 15" radius, but they might.

(I wish something like that were available in N.)

Don't know the radiuses are but Peco makes a very small curved HO switch. As for curves the Los Angeles Junction RY has a place w/ the HO equivelent of 10.8" R. Plus there's also a #3 switch there. If the prototypes can do it why can't modelers? To see how my rolling stock would work laid down a 1/4 circle of 10"R. Ran an Athearn CF7 & Atlas S-2 plus a 40' boxcar forwards & backwards w/ no problems. Couldn't do it w/ 50' boxcar w/o derailing but then there were no easements either.

If you haven't found anything yet,try the European brands like Fleischmann and Roco. I don't have details but both companies make small radius curved turnouts.
