<p>A method is being described for the installation of railway tracks onto ballast beds, which avoids the need for the installation of any type of auxiliary track. The method simplifies the method of operation of the current state of the technique in an appreciable manner, and contains the successive stages carried out after having located the sleepers onto the ballast bed, consisting in a summarised form of the fixing and laying of a pair of rails from a mini train, for the transport of the rails with the fastening and traction of same up to their complete unloading, the operation being guided by means of a discharge wagon; the support of the rails on longitudinal movement rollers; the cutting, squaring and fixing of the adjacent ends to the consecutive rails; the raising of the rail with the help of a crane, and the removal of the rollers; partial screwing of the track and placement of the rollers for the next cycle, and the removal of the tractor device from the mini train, and the final screwing.</p> |
