The quality of the alignment and levelling achieved, is thanks to the sophisticated machinery available for track and point operations. These machines are computer controlled and equipped, and ensures that the final layout of the track respects the required parameters to the greatest degree of precision. The final track treatment is also possible by means of a stabilization procedure.

 

 
The capacity to cover increasingly great distances as required by the modern maintenance sites, as well as increasingly improved traction performance, especially in the presence of considerable slope gradients, means that railways companies need to ensure that their locomotives or of power levels exceeding 2000 HP with the capacity for travelling at speeds of 80 km/h, to ensure that there is no risk of obstruction to commercial railway traffic.
