publicity stunt
The BB 9004 that reached 206mph was pulling 3 cars only, each with 50-100 people, true. The advertised 2,500mph train is actually a 6-person pod. More like a big car than a train really...
Not to mention the technical challenges to be expected (cf the difficulties to built the LHC ring). All this in less than 10 years for a tenth of current costs?? How could a train based on magnetic levitation and a vacuum tube be less expensive than normal magnetic trains, which are already a lot more expensive than "regular" trains ?? When it looks too good to be true, it probably is... very unfortunately I must say.
