Hi Mike: Constructing curves with spiral easements is actually easier to do than it is to explain in print. There are complex mathematical formulae one can use, but a flexible tool such as a thin strip of wood, or even a length of code 172 rail will work quite nicely in forming a natural easement from straight to curved track centers. The trick is leaving about a half inch of space between the tangent and the curve, and then using the flexible tool to plot a line joining the two centerlines. Track Planning for Realistic Operation by the late John Armstrong should be in every model railroader's library. However if you Google Spiral Easements in Model Railroading,and scroll down to "TRACKWORK...doing it right" by Richard Kolm, you'll find a pdf from an clinic he did in 2006. I think that should explain a lot. Good LuckJim Martin p.s. Internet searches will yield a ton of model railroading techniques.
