Hyperloop is much more feasible on Mars than on earth because you don't need to maintain a vacuum -- you've already got one. You don't even need a tube, just a U-shaped track.
Thus making it a monorail, rather than a Hyperloop.
On Mars, you don't need the top half of the hose because it's already low-pressure, so the ramjet hovercraft could run in an open-air trough.
