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 If you don’t get a better answer, there may be something in the Fascicoli Circolazione Linee or thereabouts: https://normativaesercizio.rfi.it/NormativaEsercizio/

(I can’t check right now. Mobile coverage is so bad, at one point my phone booked itself into “A1 BY” which can’t be good.)

Donet - Circolari Territoriali e Fascicoli Circolazione Linee 5.0.14

@partim @jon Also, yeah, it's easy to forget that it's a good idea to put your phone on manual network selection near EU external borders (including those of a certain country using a Latin-based abbreviation for its country code)
@HaTetsu @jon I didn’t even think of it. The line is, like, ten kilometres away from the border.
