We don't have many, to be honest. On a national level, there are only these three: Tutto Treno (both prototype and model info/articles) https://www.duegieditrice.it/tutto-treno-sommario/ Tutto Treno Modellismo (only modeling articles) https://www.duegieditrice.it/tutto-treno-modellismo-sommario/ I Treni (both prototype and model info/articles) http://www.etreditrice.eu/index2.php?itreni=sommario I'm not aware of any other. But if you're interested in Italian trains those three aren't that bad at all
Welcome back! The layout looks familiar, I'm pretty sure it was a big source of inspiration before I too went on a hiatus.
I also model SP but in HO as I like the variety of SP loco colors and styles, plus their diesels have crazy over-the-top light packages. A weathered Bloody Nose diesel has no equal on a layout.
Thanks for the tips on the magazines Denny! I found these. The pictures are super nice but Google Translate will have to help me read them
