Hello,
you don't have to do only models. Guys from there are preparing for simulator Czech locomotive 163, which is also used in Italy like E.630. When you will make photos for textures and send them to forum, I'm sure that the devs will be happy. Recently was also released model of TRAXX, so you can do textures of some Italian carrier.
If there is some community of people playing MaSzyna in Italy, or you are thinking rail fans in Italy could be interested, you can write Italian documentation for sim. In folder sounds, you can find TXT files with name ending with -en. This are files for English subtitles. You can translate them to Italian and save them with end -it, to have Italian subtitles.
Here is some post from another Italian fan. Maybe you can try to contact him and start to cooperate. He wasn't on forum about two years, but when you will write him Personal Massage, maybe forum will send him email and he will come back.
