    System (1) for change to three lanes (2, 2a) in tracks (3) in polyvalent or monovalent two-lane plate (2); for tracks (3) whose sleepers (5) comprise prefabricated blocks (6) comprising: - two replacement plates (20, 21) to replace the original clamping plates of the rails, - a first seat (22) for placing each existing lane (2), in each replacement plate (20, 21), - an additional seat (23) in at least one of the replacement plates (20), for an additional lane (2a), - means for fixing the replacement plates (20, 21) to the lugs (6), - means for fixing the rails (2, 2a) to the replacement plates (20, 21), - seat plates (25) between each rail (2, 2a) and the corresponding seat (22, 23), - soles (24) disposed between the replacement plates (20, 21) and the corresponding block (6).

    27a) for support and fixation of the existing rails (2), being found interposed between the sectors (8) and the existing rails (2) seat plates (9) provide elasticity to the assembly, and inferiorly a base plate (11) elastomer, comprising some of said plates (9, 11) first through holes coinciding with threaded sheaths (15) embedded in the plugs (6) for the coupling of fixing bolts (16) that are made by tightening on some standard clips (17) for securing the lower wings (32) of the existing rails (2).
    According to the invention, the process comprises the following steps:
    -remove the existing fasteners (threaded bolts (16) and clips (17)), ideally with a motor-washer, lift and remove the existing rails (2) preferably using mounting frames, not shown, and then disassembling the rest of the fasteners, -mount a few second caps (33) of sheath to prevent dirt from entering the threaded sheaths (15) before demolishing the concrete, -demolition of the inner projection (27) of the concrete plug (6) of the sleeper (5) of the side where two rails (2, 2a) will be installed, (see fig 2a) - cleaning of the demolished area - which will reconfigure in this block (6) the sector (8) for subsequent placement of replacement plates (20, 21) -, - disassemble the second sheath caps (33) previously placed, (in figure 3 you can see the block (6) already prepared after demolishing the inner projection (27)) - reconfigured coplanarity of the sector (8), for example by using a template, reviewing if it is necessary, -fix support soles (24) of plastic and / or elastomeric material on the replacement plates (20, 21), -fix the replacement plates (20, 21) with screws (28) to the studs (6 ) and tighten, ideally with motor-washer. -mount seat plates (25) of plastic and / or elastomeric material on the replacement plates (20, 21), in the seats (22, 23). -Place the existing rails (2) and an additional lane (2a) and remove the frames, -fix the rails (2, 2a) to the replacement plates (20, 21) using screws (30), nuts
    (31) and clips (17) standardized (type SKL for example), with tightening torque of 200 Nm approx.
