first many thanks for your great feedback! Indeed, I forgot to bring the splines I took in the Screenshot as well for giving a better overview what had happen..
I see you took a totally different approach and I am going to see if I can adapt this to my situation. Since I am really new to railclone from now, it should give me something to learn from either.
Maybe some curiosity still exists- I also attached the scene with the given parts here.
(I just mention, that I am pretty new at using Railclone)
