📋 Tender Overview
Adif has awarded the contract for the execution of the security and communications installations at the Grisén station, in the Ribera Alta del Ebro region (Zaragoza) and located on the Madrid-Barcelona conventional gauge line, for an amount of 21,632,352.5 euros.
This investment is in addition to the one currently being carried out by Adif in civil works and infrastructure at this station and, as a whole, will contribute to improving the safety and accessibility conditions of the space, with the modernisation of its facilities and its adaptation to the demands of the current and future railway service.
The conventional gauge line to Cabañas de Ebro begins at Grisén station, forming a triangle that makes it possible to run directly between the Madrid-Barcelona line, from its Madrid side, and the Zaragoza-Castejón de Ebro line. It also has several sidings, as well as an industrial siding for the Opel factory.
In order to reorganise the layout of the station's tracks and platforms and with the aim of increasing its railway operational capabilities, Adif has awarded the contract for the security and communications installations to adapt them to the new operating scheme and guarantee their functionality, reliability and availability.
This contract therefore covers the adaptation of the electronic interlocking system that manages movements within the station, the conditioning of rooms for internal use, operations on field equipment, the adaptation of the facilities at Zaragoza Traffic Control and the renewal of all communications and security systems.
New LED lighting and ASFA (Automatic Signaling and Braking) system signs will also be installed, new wiring will be laid and tests will be carried out prior to putting the new equipment into service, among other operations.
In this way, the functionality and operability of the station layout will be expanded, increasing traffic performance and facilitating more efficient operation.
Current work
The comprehensive remodelling of the station includes adapting the layout of the track bed and its route to increase the speed of passenger trains between Madrid and Navarra/Basque Country/La Rioja; and the reorganisation and extension of the sidings to provide two of them (3A and 3B) with 750 m of useful track length and to make the operation of traffic manoeuvres on the industrial siding more flexible. In addition, the platform will be extended to meet the needs of the new track configuration.
The project also includes the installation of new elements (rail, sleepers and ballast) and track devices, the complete modernisation of the electrification system and the relocation of the lighting installations. The height of the platforms will also be raised, a new central platform will be created and the main platform next to the passenger building will be rebuilt, making it more functional. The remodelling also includes the elimination of the level crossing between platforms, by building a new underpass, equipped with stairs and ramps.
The longitudinal and transverse drainage network will also be adapted; two retaining walls will be built where the embankment and platform will be extended; new enclosures will be installed and repair work will be carried out on the structure over the Imperial Canal of Aragon.
