Jon Worth · 10w The answer here, somewhere, is roughly this: any GB gauge train can run on a track rated GB But trains might *also* be able to run on smaller loading gauge tracks *if it’s checked* So Rock can run... Jon Worth @Jon Worth 1777569313 So ultimately this leaves us with two interpretations for “TGV-M is too big for Italian lines”Either there’s something about the geometry of the Rock and the TGV-M that’s different but we don’t know in public what that isOr RFI just didn’t check yetAnyway tonight I’m not going to answer this question definitively! 2
