Okay, here's what I have so far:
Attachment 6530
List:
Rectilinear sections:
straight (100m)
wave straight (100m)
straight: into banked curve left/right 30 degrees (100m)
straight: twist left, right (100m)
straight: squeeze (100m)
Curved sections:
90 degree flat r=50m/r=100m
90 degree elevated r=50m/r=100m/height variation=15m
45 degree flat r=100;
90 degree bank r=50m

I'm using Cassandra's track texture just as calibration. I'll make a generic texture for you to edit at your own will...
