The economy of a transportation systems includes the factor that is "a value of time for a passenger". It is not surprising that Concorde traveled mainly between London/Paris and NY as there the factor gave Concorde an advantage over all other competing means of transportation (for some pa$$engers).
If you would like the same to happen with vacuum trains then this might happen only in some circumstances. It has to be in a place with high income and difficult transportation network. Switzerland and Alps fits. Germany and autobahns does not.

It would have went to Hangzhou should it not be some internal political strife during and after Chen Liangyu's tenancy as the mayor and Liu Zhijun's tenancy as Minister of Railways. The control center has enough coverage built into it, and there is preallocated space for a maglev station in Shanghai Hongqiao Transportation Hub.

There was even a debate on how Beijing-Shanghai HSR should be built - railways or maglev, and in early years the maglev solution was actually preferred since it is fundamentally faster.

I got the impression that it's a much better technology in most respects, especially the elevated tracks, it just seems to be an energy requirement thing.

It won't happen at all. It's just a fundamentally stupid idea from a practical engineering perspective.

Well the current high speed rail solution eventually won because of its compatibility with the existing railway infrastructure in China. Rescuing a stuck maglev train is a lot more difficult than rescuing a stuck railway train too. And the compatibility with existing infrastructure allows traditional locomotives being used as rescue engines on HSR.

Current China HSR system also make extensive use of elevated tracks too, with 4 out of 5 longest bridges in the world being part of mainland China's HSR network (and the remaining one on Taiwan's THSR.)
