Slight variation of the theme...
Didn't Parry (of People mover fame) have the idea of a flywheel for stored energy to make the people mover errr move??
There were power pickups built into stops, to spin the flywheel up again..
I think the practical problem of a gyro-stabilised system is putting the energy into the gyro's??
Perhaps if they are in a vacuum, and use near-room-temperature superconductors, there is a way round that?
Though I for one do not want o have to top-up my 'loco' with liquid nitrogen before each run!
