I would guess that the camber of the rail bed (ie banking) would help zero out the centrifugal forces on a trail going around a bend. The bank would have to be calibrated for a specific speed. That is a first order correction. The flanges ARE necessary to provide second order nudges - which become first order of the actual train speed is different enough from the rated bank speed.

The rotation of the motor-generator set is not central to the riddle. It would set up a gyration effect that would counter any attempt to twist the engine off that axis of rotation - ye old V x F stuff that you can verify with a spinning bicycle wheel. As the resultant reaction force is perendicular to the applied force, it won't help to counter the centrigugal force. It will push the train down or up depending on the direction of the turn.

IMHO, Bill
