A solution looking for a problem.
I just cannot see how this is going to be useful. The cost of building and operating is just fantasy (although the same could be said of HS2).
For short distances the time spent at each end outweighs the advantage. For something like London to Edinburgh it will be competing with air travel, not train and the construction costs are just horrific. Air has to be better and is certainly less destructive in land use. The green credentials are dubious as well. I have no idea how it compares to air travel but just maintaining the vacuum is horrendous in energy, green or otherwise.
