Just because I started to prepare the dwg for you I got it to work with the small profile that didn’t work before (can’t say I know what I did different though).
However, im stuck now at trying to either:
-Get my Rail profile to rotate perpendicular along the path and the Sweep it to create a Solid
-Or copy/array my rail profile to given points along a given path (with points) and then Loft between them to create the solid.
is any of this possible (without connection to C3D corridor/alignment etc)?
I have only found ways to array Blocks and not how to array Dynamo Geometry, any clues?
I can attach the dyn and dwg that shows how far I’ve come.
I would recommend you to check out the class I just did in AU2019. Many possible ways you can approach this and can be done by creating a barrier corridor as well. Can be done without corridor similar to what you are trying to do extrude to a path.

(Refer to 25:07 - 27:49) - Tunnel from excel without corridor. This is similar to what you are doing but can be done. I did not explain in detail how I did it but show how it looks like.
