Dear All,
John Armstrong lists a #5 turnout as having a 11.4 degree frog angle. Assuming that the frog angle continues without turning to the divergent end of the turnout, you would need exactly an 11.4 degree turn in the opposite direction for a parallel siding.
The closest is a half 22"R curve, Item #44532 (4 per card) which is 11.5 degrees.
If you want a wider parallel spacing, a 12 degree 33.25"R curve, Item #44509, (4 per card) will work, but with 0.6 degrees of error, which is probably imperceptible.
A #6 turnout has a 9.5 degree frog angle. As Bob pointed out above, the 1/3 18"R curve has 10 degrees, which is within 1/2 degree. The problem is that you reduce the minimum radius for the turnout ("Radius of the Closure Rail") from 43"R down to 18"R.
It wouldn't hurt if Bachmann were to release a 43 or so inch Radius - 9 degree "half" curve. (Wish List)
Hope this helps.
