I mainly know the older, shallow line inner city routes. I've used the existing ?SNCF? Hookups to Orly, CDG and the Thalys North into Amsterdam, it works well. Paris was always an exemplar for modernisation in a time where the O.G. London underground was a bit moribund (rubber wheels) but retention of the carnet system beyond its life and a surge in London transport investment rather upended things.
This is a huge expansion. Being brave enough to build rings is great: most capital cities obsess with spokes to existing hubs, or like the Elizabeth line do a single slash across.
