X² has two sets of rails on its track. When this picture was taken, the innermost rails, used by the large "drive wheels" to support the train, were painted yellow. The outer, purple rails are straddled by smaller wheels which control the rotational position of the seats. The distance between the two sets of rails determines the angle of the seats in relationship to the train chassis.
The seats are not free spinning like the spinning cars on rides such as Fairly Odd Coaster or Primeval Whirl.
