Wooden Roller Coaster Construction

[Vigil]

I was not really sure where to post this, but I had some questions about the construction of wooden roller coasters specifically the fabrication of the track. I know there is the newer way of making laminate sections of track and then assembling them more like a steel coaster, but how does the traditional method work, i.e. building the supports and then layering the track on the bents? I read somewhere that the track is not actually rigidly attached to the supports, which is good for stress relief. It makes perfect sense to me that, once built, the track would be solid enough to hold its shape itself on simpler coasters, but how does that work on more twisty modern coasters like on a 90 degree banked turn? How do they start the track? I would think that it has to be attached somehow to make sure the track is in the right place, at least at first. In addition, does anyone know the dimensions of the boards typically used to construct the track (if there's even a standard)? Is it nailed together? Or bolted? Or some combination of both? Do they wet the beams to make them easier to bend before clamping them down?

 

I have done quite a bit of research already but have yet to find any super clear pictures or information that clears it up. It's quite a few a questions, but if anyone knows the answers or can point me in the right direction it would be much appreciated. Any close-up pictures of track construction would also be really helpful. Thanks!
