Look through the following link:
http://www.westportterminal.de/howtoscrcrossings.htmlCustom, hand laid crossings are an art from. I've done several - but each one was created differently. Some fully curved crossings were done piece by piece. I've also done continuous rail one route with a butted joint and then fitted the crossing pieces.
Experiment with some materials, you'll find what approach works for you.

I estimate I have about 5 pounds of coupler springs somewhere in the vicinity of my workbench.
