Hi glad you asked :) I used magnums trackpak 2 for the road and train tracks! If you go to the page for trackpak2 you should find a link to a github. From there you can download the resources including a text document describing the installation process and contents of the pack. It's really well written and you should be able to get it working from the document. But if you have more questions i will be happy to answer :)

Simple yet solid. Good stuff

How you made the rails on your map❓
I can make stuff, but I don't know how can I place rails.
