It certainly should be possible, you just need to understand how pov SDL 
works with respect to objects.  Objects don't have their own local origin 
which they rotate and scale around, this is all done relative to the origin 
<0,0,0> no matter where in the scene the object is.  So you must think how 
the piece is made relative to the origin.  Typically, you would make the 
pieces at the origin, rotate them appriately, then move them to thier proper 
location.  You can also build sections of the track like this in groups, 
then rotate and move the whole group to it's final location, depending upon 
your particular needs.

PS: Never assume something can't be done in POV.  Us hardcore POVers will do 
our best to try to find a solution no matter how simple or complex or die 
trying :D
