  "textContent": "The invention relates to a system for controlling and managing the mechanical tension of the catenary wire in rail infrastructures, the catenary being formed by a series of linked sections which are tensioned by counterweights and one of the ends of which is deviated in order to be wound around a pulley. The system comprises: an extensometer gauge (7) disposed in the section of catenary wire (Ia) deviated from the line; a box (9) with operation, management and communication electronics; an electrical cable (10) for connecting the extensometer gauge (7) to the operation, management and communication electronics; and a communication between the operation, management and communication electronics and a control centre (12) in order to ascertain the state of each catenary section in real-time, as well as the tension thereof so that action can be taken in the event of insufficient tension and so that the tension of the different sections of the catenary wire can be altered remotely from a control centre.",
