Having the loop flattened into two parallel tracks with a small
turnaround loop at each end means there'll be no net sidewards or
rotational motion due to gyroscopic, magnetic or Coriolis force,
providing the two tracks handle exactly equal and opposite momentum
transfer. But each individual track will suffer large Coriolis force,
causing the two tracks to bang against each other or pull apart or
even worse shear away causing a strong torque on the whole system.
Thus the two tracks must be carefully braced against each other to
prevent both banging and pulling away, and must be oriented so as to
minimize shear/torque.
