Are SNCF's TGVs too big for Italian tunnels?

The answer: check a map

But the problem: I do not know of a public loading gauge map for all Italian lines

Can anyone point me to one?

Grazie mille! Merci beaucoup!

@jon
I assume the answer is different for classic TGV vs TGV Duplex?
@brunogirin Yes, exactly. The single deck TGVs that run in Italy already present no issue. SNCF now wants to run double deck ones.
