REPLACEMENT OF A RIGID CONCRETE TRACK BY A CONCRETE TRACK WITH DOUBLE ELASTICITY, CARRIED OUT ON THE MADRID UNDERGROUND WITHOUT TRAFFIC DISRUPTION

RENOVACION DE VIA HORMIGONADA RIGIDA A VIA HORMIGONADA DE DOBLE ELASTICIDAD REALIZADA EN EL METRO DE MADRID SIN INTERRUPCION DEL SERVICIO

Presentation of a track concreting system in which the track is supported by concrete blocks covered by elastomer on surfaces resting on the invert and side walls. The rail rests on the lower part of the block by means of means of another elastomer of different elasticity; anchoring is ensured by elastic fasteners. This system has an excellent vibration absorption capacity whether at high or low frequency. The most outstanding feature of this method is that it does not cause any traffic disruption.
