The invention comprises two mechanism blocks 1, 2, joined to the corresponding track superstructure, composed of two bodies: the movable plates 11, 6, which are mounted in the interior of the immovable parts 3, 4, the latter serving as sliding base and support for the plates 11, 6. It allows the synchronized articulation of both blocks 1, 2 in two positions: diverted and non-diverted track. The plates 11, 6 are fastened by means of movable fasteners 31, 43, 30, 48, 58 and immovable fasteners 37, 50, whose plungers (pistons) 33, 45, 32, 52, 60 penetrate the orifices 35, 47, 62 or other contact points with the plates 11, 6, fastening them. The change in position from one track to another takes place in three stages: - release of the movable fasteners 31, 43, 30,48, 58; - articulation of the plates 11, 6; - blocking of the plates 11, 6 by means of the fasteners 31, 43, 30, 48, 58, 37, 50. Automation and remote-control systems may be installed in the diversion with blocks and it is suitable for any gauge. <IMAGE>
