Hello there!
I would maybe have interest on this project and other italian trains as well, but it is very hard to find any technical drawings of these...
The ETR470 or ČD 680 ist a very interesting vehicle, as there are so many versions around Europe: Italy, Czechia, Slowenia, Switzerland, Portugal, Spain and also Finland!
I am now in the middle of my yet biggest project for TpF, the Re 4/4 II, but as I finished with this in a few month, I will look for new opportunities and will come back to this thread as well. Who knows, maybe it will be my next project! 
Best regards
