Find the start point on the circle and move the section curve to the start point.

Nope does not work. Using 8*13 release of GH. I expictly calculated a point at the start of the persistent circle and created a persistent circle at this point. I then used the GH Sweep1 component but it again does not return a brep.

Try the Flip component. Not a clean solution, but often works.

You have to find the start point from within grasshopper after the rail curve has been created.  Still it doesn't always work.
