Abrégé
Anti-collision screen for birds on a railway track, comprising several posts (1) aligned in two alignments on the two sides of a railway platform where is located the railway track, such that each post (1) comprises a pointed conical end piece (3) in its upper part; and three metallic equidistant helical cords (4) extending in the post (1) from the pointed conical end piece (3), along a post length section between 1 and 1.40 meters, where the posts (1) are located in a staggered manner on the two sides of the railway track and separated from one another by a distance between 1 and 3.50 meters.

SYSTEM AND METHOD FOR DESTRESSING BRACES BY INCORPORATION OF, OR SUBSTITUTION BY, IMPROVED FILLER MATERIAL
The present invention relates to a system and procedure for destressing braces by incorporation of, or substitution by, improved filler material. Specifically, the method consists of removing the sheath that covers the brace and the cement slurry (if these elements are present) in an area and leaving it clean, placing a formwork around same, into which the improved filling material is injected, which makes it possible, once set, to have an area with improved strength and adhesion in order to be able to place clamps at the ends thereof and, from there, structures in the form of a yoke joined together by post-stressing rods or tendons, on which hydraulic cylinders act to release the tension from the brace and transfer it to the post-stressing rods or tendons and therefore to be able to cut the cords or wires of the braces, in order to subsequently relax the hydraulic cylinders in stages until the brace is completely destressed.

LOW-COST WIRELESS SYSTEM WITH AUTOMATIC LOCATION-FINDING BASED ON IMAGE PROCESSING FOR DYNAMIC INFRASTRUCTURE TESTING
The invention relates to a low-cost wireless system with automatic location-finding based on image processing for dynamic infrastructure testing, that avoids the precise positioning of the sensors by being based on wireless devices provided with low-cost monitored cameras, enabling the relative position of the sensors in relation to a known point to be obtained by means of the image processing.
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.
A method is described for the installation of slab tracks in tunnels, in particular tracks on a slab of concrete, with the optimised design and execution characteristics, and substantially increased performance compared to the normal known methods. The method includes a succession of phases executed in order, with the help of an auxiliary track, Consisting of the design of the construction section, the construction of the railway yards, assembly of the auxiliary track from the evacuation platform, execution of the foundation base, assembly of the track in slabs, transitions from slab track - ballast track, and placement of long bars and welding.
