Do the catenary-like tensile cables give sufficient lateral stability to the structure?
The tensile cables give a static pull on the structure sufficient to curve it down to the horizontal, as well as help keep it pointed in the right direction. The cables allow lateral forces to be transmitted from spooling motors on the surface. These may take many seconds to arrive, but they can be used to correct long-wavelength low-frequency motions that exceed the capabilities of moving counterweights near the track.
