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 would that make sense to include in openrailwaymap? Is that information published elsewhere?
@jon tangent: have you see the new https://openrailwaymap.app ?
OpenRailwayMap

@jon the .app has a loading gauge setting, and some data for Italy!
@grischard Yes, but sadly NOT for the lines I need to check!
