The tube is vacuum, you'd need an airlock not just a simple hatch, no? How do passengers get from car to airlock without a suit?

Hyperloop is not a full vacuum, only partial vacuum if I'm not mistaken. I don't know what kind of difference that would make on pressure but I assume that means that the tubes are not air tight and actually breathe.

Hyper-loop requires 99.99% of the air to be removed from the tube, so it is complete vacuum from the lethality / safety and structure / pressure perspective.

I am not sure what do you mean by 'ubes are not air tight and actually breathe', but they definitely are not air permeable.

Depressurize the tube first.
