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 https://data-interop.era.europa.eu/map-explorer if you click on a line on this map and then click on a track in the pop-up it will tell you the loading gauge

if you're doing it enough that that's annoying and no-one else has bothered, i can probably hack together a map from the data

@bovine3dom Except it doesn't, in Italy...

@jon i tried it for three different random places in Italy and they all did 🤔

are you definitely clicking on a "track" not not a "line"?

@jon i can't see any tracks without gauge listed
@bovine3dom Right, got it
