Salut Joris,
Je viens d'avoir une réponse,
Hello, you can have a look to my website: http://web.tiscali.it/seven_prog_mecc/ . As you can see, there are some models available (railcar ADe and its coach RPe). Then, in the inside pages, you can find photos and videos of Sardegna metric railwais. If you have questions about specific arguments, ask me without any problem.
Have a nice evening
