Remember that SpaceX’s own Hyperloop test track was partially dismantled to make room for… a railway. (A freight line branch because it is in the US but a train track nonetheless.) It was later fully removed, most of the land is now parking spots. Not that parking spots were all that needed (a cycle path would serve the community better but it’s the US), pedestrians were complaining they couldn’t cross the street with the adjacent tube that was too short to be useful and probably no longer could hold vacuum anyway after lack of maintenance and corrosion. Unlike the railway, the expensive tube never transported anything (with only one working airlock, test vehicles exited where they entered).
