About the second question, a solution I think of is to have different materials set to the outside and inside of the rails. One of those materials will be your usual material, the other will be a transparent one. Using different materials on the same extruded mesh is shown in some example scenes, 26_CGExtrusionExtendedUV.unity being one of them.
If you are not in a hurry, give me until next week to look deeper in the code and fix the issue the UV generation seems to have with your open shape.
