Yes, that seems to fix it!
So two more related questions: if I extrude the mesh, the poles are neatly placed on the spline. However, the offset of the rail doesn't seem to be neatly in the middle. Instead, on the right side of a circle, the mesh is placed a bit right to the spline, and on the left side a bit to the left. The idea is that the mesh is always placed in the middle of the spline, so the poles aren't off. The occurs also in the scene I sent you.
Second thing is that I wish the rail to be invisible from above. This was achieved due to backface culling when it wasn't closed yet. Is the way to go here to create to sides of the rail and extrude those seperately?
Sorry for the huge amount of questions. I'm trying to grasp how this all works. Hope you don't mind.
