>>2057842TGV 001 is peak "what if train, but racecar?".
I love it for what it is, the last iteration of a concept that only worked as long as oil costed nothing, but am still kinda glad it died when it did, allowing the program to transition to electric power before sunk cost kicked in.
Had it gone through, we'd also never have had the opportunity for the absurdity of the direct Paris - Les Sables d'Olonnes service that used to imply towing a TGV with a diesel over the last leg as that line was only fully electrified in 2008.
