Telecom and energy system improvement on Madrid-Sevilla HSR

Madrid-Seville high-speed railAdif Alta Velocidad has launched a EUR 77.7 million tender for the telecommunication and energy infrastructure works for the entire Madrid-Seville high-speed rail. The contract will have a duration of 48 months.

The winner will provide and install new fiber optic cable along the route and will improve the power supply system and the signalling and communications system.  The 750-volt alternating current power cable will be laid on both sides of the platform between Madrid and Seville, doubling the supply capacity.In addition, there will be the replacement of power panels, transformers, uninterruptible power supplies and batteries, among other facilities.

The contract covers the renovation of the facilities to maintain the rail services and to improve the availability, the increase of line’s capacity and regularity of train movements and the rationalisation and optimisation of railway operations in accordance with the needs of the operators.

The Madrid-Seville high-speed rail was put into commercial operation in April 1992 and is the first high-speed rail connection in Spain. This line continues to provide its service with the same level of quality with which it was conceived thanks to the application of a strict and rigorous maintenance plan during the years. Based on the life cycle of the elements, it has been considered necessary to carry out various tasks to improve the superstructure, which will ensure that the line continues to offer the high standards of reliability and comfort that it has offered up to now in the future.

In this context, the deployment of the ERTMS Level 2 has been planned in two phases. The first covered the Madrid – Córdoba section, and the second, between Córdoba and Seville.The installation will be carried out in coordination with the installation project of the second layer of the GSM-R mobile communication system, as well as with the construction project for the laying of fiber optic cables and for the installation of the power lines.

The project is financed by the European Union under the NextGenerationEU recovery plan. Adif and Adif AV have previously authorised various tenders or contracts which will be financed through this mechanism, for a global value of EUR 556.66 million (VAT included). Of this amount, EUR 479.39 million correspond to tenders, while the rest correspond to contracts awarded.
