The electrical substations will be renovated, which adds to the work on the electrification system, already underway
Adif AV has awarded two contracts to renew the Madrid-Seville high-speed line, for an amount of 52.2 million euros. The first of them, for 38.7 million euros, is destined to the modernization of the electrical substations, and the second, for 13.5 million euros, to undertake the second phase of the renovation of sleepers.
(07/02/2024)
The contract to reform the electrical substations includes the renewal of the main elements, that is, the transformers, of 11 of the 12 installations of this type that the line has. An action that, at the El Hornillo substation (Madrid), is already underway. The consortium made up of Elecnor and Electren will be in charge of carrying out these works.
Along with this investment, Adif is renewing other elements of the high-speed line electrification system: the replacement of some elements of the overhead contact line or catenary; the installation of LED lighting in the tunnels; and the deployment of a double high-voltage cable on both sides of the line to power its signaling and traffic management systems.
Second phase of the renovation of sleepers
The renovation of substations is one of the milestones that this year will drive the development of the comprehensive renovation plan, which will keep the first high-speed line in Spain at the forefront, to continue responding to the challenge of liberalization and new mobility models. .
In this sense, Adif has just contracted the supply for the second phase of sleeper renewal for 13.5 million euros. It advances in another strategic area, signaling, deploying the ERTMS level 2 signaling system, the most advanced in the world; and addresses the last phase of the renewal of track circuits.
In recent months, in addition, the first phases of the renovation of sleepers and detours have been completed; the modernization of the line’s nine viaducts in Sierra Morena; and the improvement of the maintenance bases, with that of Calatrava already completed.
The comprehensive renovation of the Madrid-Seville high-speed line affects all areas of the line: infrastructure (viaducts, tunnels, drainage, etc.), tracks (sleepers, ballast and turnouts), signaling, telecommunications, electrification and protection, deploying the latest technologies and equipment.
Currently, 75 percent of the planned actions are underway or completed and almost all of the investment, more than seven hundred million euros, has been mobilized.
