Curved Diamond Crossings

[nachoman]

I've never tried. I don't know any reason why it wouldn't functionally work, but I don't know how prototypical it would be. If you are an experienced track builder, it shouldn't be that hard to experiment and build one to see how it works out. You don't need a template or a jig if you know what you are doing (although it would help). I think you would want to accurately bend the rails to the right diameter before construction, though. I figure that could be the hard part - to make sure the curve is smooth all the way through.
