Right now every time I extrude I can some very strange shapes. The best I can mange to get is for it all the geometry to come to a single point at the top of the curve, and thats only when I have 1 division which isn't much of a curve. I'm working with polygons and using maya 2011. If this can't be done using an extrude on a curve perhaps someone has another suggestion as to the best way to make a wall for the length of the track. The only catch is the wall needs to slope up almost like a half pipe.
