It has not yet been noted here that Richard Branson's Virgin Hyperloop One, the most significant Hyperloop company, has abandoned its plans to carry passengers. Half its staff were sacked in late February.

This is good news, especially for railways. Hyperloop was always going to be a white elephant, while diverting funds and approvals from railway projects, even if it ever got regulatory and planning approval other than in nations like Saudi Arabia. The UK DfT has been rightly dismissive of it.
It is hard to believe that Elon Musk took it seriously himself when he revived the vehicles in a vacuum tube idea, and he has not taken any significant stake in it. His 2013 white paper is full of technical whitewash, for example he claims the thermal expansion of the tube would be "absorbed" by dampers, and he does not explain how the pods' emergency brakes would dissipate their enormous kinetic energy in a vacuum; just two examples of the flaws that a non-technical person (like a typical financier or politician) might not notice.
Musk has a personal vendetta against railways and the real purpose of his white paper was as a weapon against the Californian high speed rail project. He makes that clear in his introduction. Opponents of HS2 have also used it, claiming that Hyperloop would make it redundant (although they would oppose a Hyperloop even more).
The Hyperloop passenger safety issues have never been satisfactorily addressed, and are not likely to be without drastic changes to the original concept. Virgin Hyperloop One has conceded that freight (it would need to be small) is the best way to go forward with this, if at all.
