It's one thing to set test records with test equipment, and another to set them with production equipment -- this model is the actual train they're going to run

It's one thing to set test records with test equipment, and another to set them with production equipment -- this model is the actual train they're going to run on the line. Kind of like how the Bell X-1 was the first supersonic aircraft, but the Concorde was the first commercial supersonic aircraft. (And I have a sneaky suspicion that Japan's maglev, running in a depopulating country with economy in a terminal downward spiral, will end up as marginal and unprofitable as the Concorde, but that's another story.)
