Trackmaster Revolution (TMR) New releases

[Super]

Just thinking off the top of my head, I am wondering if the toothed wheels on the rolling stock is a way to correct the Revolutions light weight cars habit of flopping around and flying off the rails going down hills and performing the tricks in some sets. Maybe this, in combination with the Revolution track, gives those cars a more gripping feature without the need to redesign the whole car. Maybe this will be the norm for all future releases. Of course this doesn't help those who run the Revolution stock on the Tomy blue track or the original Trackmaster track.
