The renovation of the track superstructure of the southern section of line 1 of the Madrid Metro, between the Sol and Valdecarros stations will begin on April 3. This project obtained the approval of the Governing Council of the Community of Madrid at the beginning of February 2023 (see news). The contract to carry out these works has been divided into two lots. The first of them is related to the comprehensive renovation between Sol and Atocha, while the second refers to the works on the Atocha and Valdecarros stations.
The first stage, of approximately three months, will be dedicated to carrying out a series of preliminary works, at night and without affecting the service, to collect material and prepare the road for subsequent actions. In the second phase, of a maximum of 129 days from next summer, it will require the temporary closure of traffic between Sol and Valdecarros.
The execution of this project includes the elimination of the ballast and the wooden sleepers and their replacement by a new concrete platform, for which the rail fastening and support systems will also be renewed, and new high-tech track devices will be installed. . In addition, the drainage system and the geometry of the route will be improved to reduce maintenance work and possible incidents.
The objective of these works is to improve the operation of the line, which will result in better travel times and greater comfort for passengers. The renovation of the superstructure will reduce vibrations and the greater technological features will increase the reliability of the facilities, in addition to reducing track maintenance costs, among many other aspects.
