The Sweep2 component of Grasshopper does artifacts that the Sweep command in Rhino doesn’t create. Can’t understand what is wrong with Grasshopper?  
Note, if changing the location for the crosssection it may help

Is this better? For some reason I’ve never been able to figure out, `Sweep2` in Rhino is much more intuitive about what you want to happen than GH. In GH, I commonly have to fiddle with curve directions that I never worried about in Rhino. All I did here was flip your 2 input curves.

What?))) Thank you, it’s defiantly better, but it could not occur to me I need to flip both curves, what is wrong with the original directions?

You’ll probably get a better result when your section curve is located at one of the start points of rail…
