I am trying to write an include file which will have a collection of Model Railroad
Track (HO Scale) to play around with in some scenes I wish to work on. Well I tried
this a long time ago but ran into trouble with the curves. I was able to get it, more
or less, using CSG; but this time I was hoping to be able to do things like extrude a
shape (say an I shaped rail) along a curve for a given circumference. Assuming I can
do that, I also wanted to place the Railroad ties along the curve as well (but I think
I can beat that problem with translation and rotation).

Any ideas on how I can go about this? Beyond using #declares and #whiles, advanced
Pov-Ray syntax has be a bit baffled.

Cheers,

Tim S.
