Help with rail tunnel alignment

Hallo, I am new to Dynamo and Revit. up to now I use mostly Autocad and Civil. Now I need to prepare a “BIM” model in Revit. I found that best will be to use dynamo. I did search on internet for more than a month and try to prepare 50 different dynamo/family files I found tutorials and blogs but none work.

Can someone show me the correct way? Some say you have to use adaptive family in non adaptive family and then you need to stick it to another family…so I am lost.
I would like to have just tubbings (tunnel lining) and a rail tracks (no need to be adaptive it will not change) and than make it along alignment and just to have a separate tubbings so it will show number.

In future I would like to add rail track cant and cross passages.

Thank you
