Expert savegame for Learning

[unseen4ce]

I have noticed that there are some very complex system designs on an OpenTTD wiki, with screenshots of such designs.
Here are some of the systems I am referring to:

I was hoping that someone has a savegame, or can point me to a savegame, with such designs so that I can learn them for myself.
Cheers
