Tunnel sample model

Hello together,

I am new in this area. Normaly I am working for mechanical engineering (automation). Is there any model or sample of a tunnel? Where can I find informations about how to build a parametric tunnel?

Did already read and viewed some tutorials. The aim is to build a complete tunnel with all informations like stations, cables, road, train etc.

Is it fast enough to work with an Excel sheet or is it better to work with an SQLite?

Thank you very much
