it this weekend...

Instead of containers on a track, have a horizontal spinning wheel, suspendedoff the ground by cables, to a central pillar. At the top of the pillar would bea set of very large bearings to bear the load.No rolling friction or wear & tear on any wheels or track. There would be wear& tear on the bearings of course. There would also be balance issues.

Right. When I say "track" I'm assuming maglev, with wheels only used as
emergency backup. But a suspension structure is an interesting idea.

The center is not travelling fast butjust rotating. Sort of like a rotating space station is orbit, arrivals and departureswould be done at the center.
