QUOTE: Originally posted by rrinker Typically, this is correct - you don't really need an easement from a turnout, because the substitution radius for usual turnouts is much greater than the radius of the curve, giving the effect of an easement. Per Armstrong, the Atlas Custom-Line #4 (more accurately a #4.5) has a substitution radius of 36", a standard #6 is more like 56"! So unless you are using VERY large radius curves, the turnout diverging route should provide plenty of easement.
