* The locomotive's driving axles are located in two bogies, each with three axles.
* Each group of axles has a vertical movement system from the central axle, independent of the chassis and the sides of the bogie.
* The six central axles, of which four are driving axles with contact points, have lateral movement to allow circulation on reduced radius tracks.
* The moving part of the hoods has a complete articulation of its parts:
* The hood is integral with the rigid base of the bogie motor and rotates with it in curves, independently of the locomotive box.
* The hood has a longitudinal movement that allows its separation from the box, facilitating turning in curves with very reduced radius.
* The bogie carrier under the hood has a rocker movement in height on its axis and a wide longitudinal movement range with respect to the axis of the track.
* Two driving wheels of each bogie motor have adhesion rings to improve traction.
* The design of the locomotive allows efficient handling on all types of curves and reverse curves, guaranteeing excellent ride quality and a great optical effect.
* The sides of the bogies are detailed, including the reproduction of sand tubes and fine pipes.
