A potential solution to running out of chain links would be to eliminate them

A second alternative to specialized chain links -- and one I haven’t tried yet
-- would be Technic link-arms and pins, threaded around large-diameter tires.
The magnet-holders can then be pinned vertically, and the curves in the “track”
aren’t so abrubt.
There might be a problem keeping this chain taut, although there are enough
wheel-diameters available for experimentation. Also, the tire-chain combo
wouldn’t move as smoothly as chain links-gears, so some extra gearing-down might
be necessary.
This is still necessarily 2D -- I’m not sure if it can be extended to 3D (a
track with hills). There might be linkages that would permit both horiz and
vertical (alternative) movement in the chain, but the extra floppiness might
cause it to fall off the wheels.
Now, how to adapt this to a moving sidewalk for minifigs... And I wonder if the
scheme would work vertically? --E.g. a loop of elevator cars moving up the side
of a skyscraper, or one of those sci-fi moving ladders (e.g. “Star Blazers”).
